Don't worry, this isn't about you.
It's not just that you don't know yourself. That's what I thought it was, at first. The real problem here is that you are sure of absolutely nothing. You're being pulled in so many different directions, and you can't figure out which way is the right way to go. And it's not that you can't decide because every choice is just as appealing as every other. You can't decide because you are too spineless and would rather please everyone and get everything that looks good rather than just finding out what you need and going after that. Maybe you're a victim of your past. But then again, we all are. I've never seen anybody as far gone as you. You're too scared to try anything difficult and too stupid to learn from your mistakes. I really hope things work out for you, because I like seeing people overcome and succeed and truly become happy. But now I'm sure that you don't have it in you, and I won't be surprised if you turn out to be a disappointment to everyone you know, and especially yourself.
