I just read through it all and realized you're just 23! I don't think you should be so hard on yourself. I thought you were like 40 and lost with no hope. But at 23? Come on.... Just get yourself a simple job for a bit. Take a break. What do you have to lose? Once you sound a little less burned out, you can give startups a shot again. Have some patience, and please enjoy your journey; you only get to do it once.
