Whats wrong?? T.T

Ive been in i guees a "funk" for the last couple of days. Just seeping in and out of depression. I have a really amazing friend who no matter what keeps trying to put a smile on my face. But for whatever reason it only lasts for a few hours. The other night i was up in my house alone (my brother was asleep). Me being alone is the worst possible thing. It gives me too much time to think about things that ive tried to burry forever.

I owe my friend (Benji's what i call him) a lot of thanks. He texted me almost all night just listening to me say how im worth nothing and how no one cares. I cried myself to sleep that night.

I know I have a problem with slipping in and out of depression. But im not sure how to deal with it.

Help?
