don't worry there are so many ppl out there like you.

I'm glad i overcame it, socialize with people can be very fun, if you're talking with the right person.

my advice is, practice to start a conversation(i'd prefer to ask smtg abt him/her), don't wait. don't be shy, if you're afraid of eye contact, stare at the area between eyebrows (I know it's weird). then more and more attempts and practices.

most importantly, stop thinking that u have this anxiety. enjoy
