Severe anxiety and depression here's what I've tried...

I'm not sure, except to remember that, 'this too shall pass'.

I'm unmedicated, save for the case of beer I've been working on. I'm in the same general boat as you, anxiety about my work is not only justified at the moment (for a change, I'm also very paranoid) but extreme. I don't know what's going to become of me, atm.

Suicide ideation... I mentioned that in the OCD forum, just a little bit ago. Having a lot of that, yes. A desire to escape. I don't really wish to be dead. I think. It just seems like a nice escape, at the moment.

You're taking meds, and going to therapy. Something I envy, right now. I think giving those a change to help, is the best thing you can do at this time- just stay the course. I... am very tempted to try and get some professional help, myself. Like you, I don't know how much more I can take. One thing I've found, however, is that we can take a lot more than we think we can. I think because a lot of times, we don't have much of a choice about it. I remind myself, or try to, that it could always be worse.
