Here are yet some more options for your career. Happy, birthday, by the way! I know how it feels to think your a total waste. It's not common in young people. But clear your mind, move your troubles aside and stay on the optimistic side.
First, try returning to university/college. I'm pretty sure it's ok to do that. Finish your courses.
Then try out for some job interviews. Getting a stable income is the first thing you need to do to progress in true adulthood.
After that, try and find a wife. Don't worry, it will probably take some time to find a match. If you get heartbroken, accept it, and then get over it. Pretend it didn't exist.
But for now, enjoy some quality time with family and friends, and cherish the moment...
Happy Birthday again!
