I think i have social anxiety

Hey sythe ive been thinking and researching about it alot. ill give you some background knowledge of myself

I am 18 years old im a senior in high school i recently moved highschools my old highschool i didnt have many friends i had a few but they werent close to me i knew quite a bit of people but never enough to actually sit with them at lunch or anything i sat with a couple of my friends at lunch and when they werent at school i would just go sit alone somewhere even though i knew people that had empty seats i still wouldnt go sit with them i would get to nervous
Im really bad at meeting new people ill act normal in all but i wont be able to hold a conversation because i feel like its going to be stupid what i say ect.

I cant meet new people i never went up to someone and just introduced myself im not that type of guy im shy. Im not bad looking i have a few insecurities but who doesnt. I had a girlfriend for around 10months i lost feelings for her but i didnt want to break up because she was really the only person i had at the school and once i did break up with her i moved schools to a school that i have a really good friend in ive made a few friends but only because of him. i dont really have anyone else at the school im usually the quite kid. im like the kid that doesnt talk because of course ill talk if you talk to me im very respect full im pretty funny to the people that actually know me.

I play games alot on the computer and have really good friends online people i knew for years and years.

Ive been trying to grow out of my shyness but it isnt easy i always feel like people are judging me or saying things about me

Just the other day i had a docs appt my stepdad told me to go sign in i started feeling anxiety my chest got tight just because i had to go sign in i felt pathetic.

I havent been diagnosed with social anxiety for the reason being i dont know how to even bring it up with my parents and i dont want to be put on medication i just want to grow out of it.

Im not a doctor so i cant diagnose me with it but i have a strong feeling that i do

I just want to be able to go up to someone and just say hey my name is james but i cant

Do you guys think i have social anxiety and do you have anyways to cope with it ill really appreciated it. Thank you.
