In every relationship I've had friendship, romantic or otherwise I feel like I'm always the one putting in the effort, going the extra miles, helping and listening when they have a problem. 

But when I need help or an ear to listen or a shoulder to cry on no one is there. I'm an inconvenience, an annoyance or they are too busy.

Why do all my relationships end up like this? How do I find people who love me back?
