Why do I always get a sudden bad feeling when I am in a crowd?

Maybe it's because you associated crowds with some particular feeling at some point in your life. The best way to understand this is relaxing and concentrating on what is really bothering you. Talk to your mind. It won't bite.

You always get a sudden feeling when your in a crowd because there are lots of people and your scared your gonna say something stupid.

It could be that you are overthinking things a little to much or that you have been doing it so long

Well,I feel bad when I am in a crowd because I am self conscious and I think about the way I am perceived by others and analize every move I do.I think that my problems come from a lack of self confidence.

That's for you to answer. The main reason might be that you don't feel safe. You might just be paranoid, fearful, or even self-conscious. It's completely normal to feel this way sometimes. Just remember that fear only exists in your head - it's a thought, not reality.

Although I cannot evaluate that this is what you are going through, I get a similar feeling with my anxiety and my therapist had said, because I struggled with this as a little girl and even around friends and family, that my anxiety may be more apparent in a social setting, thus social anxiety. Sometimes this causes me to panic as well, from being so overwhelmed. There were many more factors about my life that I had to discuss with my therapist to receive that evaluation, though, although this feeling sounds similar.

You could be feeling anxious, which often appears with feelings of dread or a bad feeling. Perhaps this could be due to a discomfort of being around lots of people.

The amount of people around you at once overwhelms your brain, along with your anxiety and other problems. Your brain cant handle it so it sends signals out to the rest of your body that you need to be scared.

Social anxiety causes people to feel bad during crowds. Like, when I am in a crowd, I feel watched and alone and I wish to go to a space with more space.

It may be that you have social anxiety, or you just feel uncomfortable in crowds. That is something very common that most people have to deal with.
