As I've read in the main subreddit, a girl doesn't love you for you. Her love is conditional on your behavior. I've recently gotten into a nasty fight with my parents (I'm 18), and feel isolated from them as well. The friendships I have with my friends are surface level at best. I feel alone and vulnerable, and I fucking hate it. I'm coming to terms that the only person who truly loves me is myself, but I feel like I'm not strong enough - that, in one way or another, I'm depending on validation from others.

How do I break this? Where do I start? If its in the beginner reading, what specific piece? In advance, thanks for pointing me in the right direction.
