You're still young and you should put your studies first before all that hand holding. Your social anxiety may well go while you're maturing.
When I was your age I thought I was the ugliest person on the planet. I used to walk with my head down so no one could see how ugly I was. I couldn't wait until I was 22, a magic number when things will be better.
Guess what? It was, the moment I turned 22 things got better. I wasn't beautiful but I wasn't as ugly as I thought.
Nothing to do with being 22, more to do with maturing attitudes.
Good luck, you'll get all the kisses and hand holding when you're ready for it.
