I'm depressed and need advice, any suggestions?

I’ll spare you the details of whats got me into this, but the gist of it is I’m incredibly depressed. I’m not sleeping well at night, taking long naps in the day, hardly eating anything, and crying uncontrollably at night. I’d be lying if I said my recent break up was not a root cause of this, but I feel there is more too it, as everything just seems hopeless. I feel like I’m crawling in my own skin, and I’m just sick of where my life is and what I’m doing.

Has anyone got some advice, or suggestions, or anything to help me?
