hi there just seeing if i have paranoia or if its possibly summin else. im not too educated on all this so any advice/opinions would be great..

ok ...
1.very consious when out in public what ppl think of me/judge me ect.
2.when in a conversation with someone if i see like a negative body language reaction from them or if they get real nervous i get really paranoid/feel stupid
3.scared to see ex gf's from years back as ive put on loads of weight and wouldnt want to be laughed at
4.i stay in alot now and i quit my job as i do have anxiety and low self confidence.. my friends wondered what happend with me as i hadnt been going out with them and they found out i had anxiety ect.. and i feel if i ever see them out in public id feel below them and they would maybe try to rub it in and think they are better then me ..
5.hate standing in shop/market ques waiting to be served as i get really paranoid/anxious what ppl might think of me /judge me ect.

is this paranoia or would you say its more of a self confidence issue?
just wanted to have a little clue before i go see a doctor

ps.im even paranoid about what the doctor might think of me ect.
and i dont like ppl to feel uncomftable around me /coz then i feel the same as they do
hope this makes sense lol
thanks all
