I'm currently receiving systematical therapy and two other kinds I don't know the name of in English, for me it's to early to tell if it's working since I just went trough the whole diagnostic period, and just started it. I do think you should consider therapy or any other kind of help before suicide, that way you can at least say you have tried everything. Though I'm not sure if sticking around long enough to see if it helps works for all of us since we're all different.
