Dude, you're 14?

Don't worry so much. Kids go through this kinda stuff. It's normal. I did. Regardless of whether we label you as borderline or depressed, just try and chill. If a relationship doesn't work out, use it as a learning experience and move on. You're going to think a lot of girls you meet are awesome, and probably a bunch of them are. When it doesn't work, figure out why and refine your approach next time. Look at it as a game that's fun instead of some life-or-death situation.

Reading about borderline and stuff can be interesting and useful if you're really deep into this stuff, but if you're just forming your personality and are still flexible, just go straight to the core by loosening up on yourself.
