Why do I freak out in relationships so easily?

Maybe because you can't trust that person you're in a relationship just yet. Just learn to trust that person, and let them know you don't wanna rush anything.

Maybe because you are scared to lose that person. Are you jealous? Maybe you never found the right person or you are in a rough period of time where all your emotions come out at once as soon as something more exciting happens

Can you explain this a bit more? Are you saying that, when you start getting close, you start self-sabotaging. What do you start telling yourself when you find yourself getting close to someone?

You may be nervous about messing something up or trying to be perfect for your partner/friend, it's fairly normal to want to be good in a relationship.

This happens to me in relationships a lot. When you start to freak out, try and see if there are any triggers that make it happen. Additionally make sure you communicate with your partner exactly how you’re feeling. They shouldn’t be offended, rather glad that you trust them enough to share this with them.

Its because you've been hurt before. You've anticipated every situation to turn out a certain way, and your reaction comes accordingly.

It is completely okay to get nervous in relationships, it's normal. You may just need time to get comfortable with being yourself around the person and then you shouldn't experience nervousness.

It might be that you haven't been clear enough about your boundaries and are afraid of your partner overstepping them. This is extremely common in relationships. Try to talk to your partner about what's scaring you and discuss what you two can do about it.

There could be some distrust between you and your partner. Try figuring out why, and discussing it.

Sometimes it can be due to what you have expierenced in your past which can cause you to freak out, freaking out in other terms could be anxiety and worrying about what could happen even if a situation hasnt even occured yet . But remember you are not alone in this as alot of people around the world suffer from the same problem you are facing, I am one of them people so i understand completely how you feel. Maybe it would be best to talk to someone like a doctor or if thats too much for you talk through it with your partner and try and come up with a plan on how you can both move forward from what you are experiencing.
