Girls....they cause me a lot of problems

there's a girl I'm intersted in,we're friends, and I've been wanting to ask her out but she's been sad and she's had a lot going on lately,I feel like I'd be taking advantage of that and I don't want to take advantage of her
I hate not being around to help her,I really care about her and now its making me feel bad as a friend and well,for other obvious reasons...

Another thing, there's this girl I used to like from last year and I saw her alone the otehr day and so I started to talk to her,nothing wrong with that. My problem there is that while I was walking home yesterday I passed by her and her friend,usually she gets a ride home and her friend walks. As soon as I pass by her friend starts to walk home...and the girl that I used to like is still waiting for her ride home...I'm thinking she sent her friend to follow me or something

fuck I think I gave her false hope...

christ, I always wonder "why do I care so much about this stuff? I've never had a girlfriend and yet when there's someone I like I just can't let go and have to try my hardest to be with them..."

sometimes I want to just give up,but at the same time I can't....
