Nothing is wrong with your CS skills, you have tried many things, most devs start with less experience than you and still get good jobs. You're confusing marketing fueled life stories on linkedin with real people. Don't worry about starting and abandoning personal projects, we all do that. Believe me, it will be easier to build nice things once you will be paid for it.
Also you should start some hobby that makes you meet people, for example a martial art (there's something for everyone, don't trust stereotypes), it will help you grow your social skills in a controled environment which should make it easier for your social anxiety.
We've been there, it will get better for you too.
