I was in your position 7 years ago.
I was single, annoyed at myself for having social anxiety which made me nervous around people, especially new people I didn't know. I had 0 luck with the ladies which always left me thinking will I always be alone?
Then I just stopped worrying about it - I dont know what made me do it but I stopped focusing on 'trying to find a girlfriend' and started focusing on myself.
One night I got drunk and thought tinder would be a good idea for some reason - swiped right (or left(?)) on people and forgot about it for a few weeks when I opened up a few weeks later I found I matched to someone and that someone has been my girlfriend for 7 years (and counting).
You're only 22 - Its ok to have standards, but its not really ok to be judgemental.
Take a step back and start focusing on yourself! I firmly the trick to finding love is to start loving yourself first.
