Sounds like you have a form of claustrophobia when people are too close to you in line . Then there is Enochlophobia , phobia of being in crowds,

I have social anxiety. If I’m with someone in a public place then I can deal with it better, otherwise I m off by myself. I’m very uncomfortable around people…that’s an understatement. They’ve done nothing, it’s me.

Social anxiety is still a phobia. Can turn into enocto type cause panic attack etc.People need help for this social anxiety type phobia from real Drs not me, you or others opinions.

It is social anxiety to feel this way no matter why.Phobia you can either live with or try to get by to feel normal round others. Say its not from having epilepsy then why? Realize people are people in crowds or not. See how some just feel this goes hand in hand with epilepsy but doubt thats true for you. Try to talk to others instead of shying away to help self relax bout this mentally like normal self should.

Its not weird at all I usually either go outside and sit down or stand by myself
