<human>: Give me the gist of the text in a nutshell

I've always had depression issues. This one just keeps getting deeper. He left me because I drank, purportedly, and started a relationship with my "best friend" five days later. How could he ever have claimed to love me then do that? How could our relationship have meant so much to me and so little too him? 

I feel worthless. I've been in bed for 14 hours and can't get out. I'm having trouble getting to work during the week. I'm in therapy and on pills and they aren't doing enough. I've spoken to my doctor. Basically I just get to wait it out and not kill myself. For what? To just go through it again?
<bot>: it's been 3.5 months, he moved on to my "best friend," I'm still terribly depressed and want to kill myself.
