As if You Were All I Needed

I have depression, I have anxiety, I have insecurities, sometimes I feel like I have nothing in my life worth living for.
My parents fight all the time, and it drives me crazy and I start to cry. I'm practically invisible to everyone, only time I am visible is when I get bullied. My family pays no attention to me whatsoever. A person that I've liked for years doesn't know I exist. I pass him in the hallway, I'm in Earth and Science with him along with him having counseling sessions before mine, since we have the same counselor.
Bottom line, I don't particularly have a decent life. Pretty much sucks as you can see. I don't think I can make it the rest of my life, what's there to live for. But there was, you'll just have to go ahead and find out who changed my life.
