It sounds like you are trying too hard to feel validated and you want immediate success. You have written a very long piece including your entire background, the success of your peers compared to yourself, the positions and awards you have gotten in various competitions (for better or worse). You sound entirely focused on accolades and achievements yet you have only been going at this for at most 1/2 years.

You need to calm down and slow down. You are only 22/23. You have so much time ahead of you and you have to walk before you can run. You have burned yourself out by too high expectations. It's not as easy as having an idea, hacking away at it for a few months and then reaping the reward.

I would suggest lowering your expectations over the short term and trying to come up with some realistic goals for the next few months. Not "launch great project in 6 months" but "talk to 5 people about the validity of feature X in the 7 days" etc.

You've already helped yourself by acknowledging the problem, writing about it and telling your family and friends.
