Why do I have a gut-wrenching feeling down my stomach after a friend told me something I disagree with, not physically, but emotionally?

You are feeling possibly bad to disagree in person because it may hurt your friend. Try to relax. Clear your thoughts

Fear and anxiety of conflict are powerful emotions. Fear that they wouldn't like you if they knew how you felt or that you might upset them. Anxiety about an impending argument or the thought that you are hiding something from your friend. Good friends find way to have a relationship despite their differences. The type of people you want as friends will accept you along with your conflicting opinions.

Its just your intuition, maybe which is probably a good thing by being your own guide as to what you should do, as you alone know what is best for you. Perhaps, it is a wise thing to heed it. It is emotionally draining you, apparently but do try to not let it keep you down. Staying positive at all times is needed. The feeling is understandable and your sensitivity to it is noticeable. You don't have to pretend to asgreevwith what you don't but being diplomatic has always been an ideal thing to do. Talking to an expert can help you more, if you need some additional support in this matter.

the muscles of the gut are strongly connected to the emotional centers of the brain. this is an ancient physical response to threat, or fear. sometimes our bodies need to react faster than we can think things through, and this response to tighten the stomach to retain food and balance, or even to eliminate a burden in the gut, is primeval, very deep seated. i like to think of emotions as Indicators, telling us something that our thoughts are too slow to process. so, consider what your friend(s) is telling you, is it threatening to something in your life, or perhaps frightening in it's resonance with something that has been traumatic? perhaps it is some other kind of Alert, for an emotion i don't think of right away, but if you stop and examine your feelings, i am sure you will have the answer to your question.

It sounds like you might be experiencing anxiety over a potential disagreement with your friend. Perhaps what they said does not align with your moral code, or their beliefs invalidate something that is important to you. This feeling could be anger, fear, indignation, betrayal, or another unpleasant emotion manifesting itself. If you explore other times in your life to see when you have also experienced this feeling, it might help pinpoint what emotion is causing it. Emotions can manifest themselves in a number of ways, and sometimes the experience can be overwhelming. It's alright to experience these feelings, they are natural and sometimes helpful in finding what topics make you angry or anxious.

Because they are not totally wrong but I have strong reason to stay firm on my opinion. The feeling of torn apart between pushing my idea to them and coercing that they are wrong or letting them with their own ideas which make me feel like letting them on their own device. I care about them to voice my own opinion, yet i also need them to hear mine and see that what i am trying to do is 'meeting in the middle', not confronting and belittle their ideas. I am still struggling as to why they prefer to attack when disagreeing with me

I was thinking of a personal example, one time when a friend and I were discussing some event in our hometown. While we were talking, she said that she could understand why some people may have been against that event and what it expressed in terms of social and cultural views. I still remember that feeling in my stomach. My guess is that we choose friends also because we feel we share some values and beliefs. And sometimes, certain kinds of disagreement may reveal that we do not, in fact, share all the same values. In that moment, it felt almost like a betrayal to me, but the betrayal of a silent agreement ("We both put value on the same things") that we hadn't really discussed until that moment.

Words are powerful because they carry so much weight and evoke strong emotions. You’ve had an emotional response to what your friend has said because you feel so strongly about the statement. So take a moment, and figure out what exactly they’ve said that caused that emotion within you, and from that you’ll have an understanding why you reacted how you did. It’s only natural to react in situations where someone has said something we strongly disagree with, and despite it sometimes feeling like a physical sensation, it’s just our own moral compass reminding us that whatever they have said has caused an emotional stir within ourselves, which helps guide us and helps us figure out how we feel about difference situations, and whether we agree or disagree.

There is potential between the two friends to get into an argument and ruin what was a perfectly fine friendship. If there is a disagreement, that may turn into an argument between the two friends. In my experience, I have been in these situations before and sometimes people will bring things into the argument that do not belong there. For instance, they could start attacking the other person about things they did a long time ago in the past or things that are irrelevant to the original issue. I believe the gut-wrenching feeling is a response to a fight or flight case and adrenaline because of what was previously mentioned.

That’s normal, everyone has their own opinions and even though your friend might have told you something to help you out and you might not like it they mean no harm and just want what’s best for you. It could also be that in the position that you’re in it makes it seem that those persons words are impossible to accomplish and you’d rather not agree with them. And that guy-wrenching feeling is completely normal everyone gets especially when they’re nervous or they know somethings wrong but you don’t have to fear about that if it’s a friend you trust because usually they just want to help out to get you out of your troubles
