I've been really down for the last 20 months or so, and for the most part I've been able to handle my emotions, but recently I've just been in the gutter. The last few weeks I guess. I'm not finding anything really enjoyable anymore. Yesterday I just had these really, really dark thoughts about... Ending it all I guess, that I could not get rid of, no matter what I tried. I'm scared of what I'll do to myself in my sleep, and I haven't slept at all since Saturday. Any help?
