chronic severe treatment resistant Major Depressive Disorder...that is quite the mouthful! All you need to say is "treatment resistant major depressive disorder" because MDD is chronic in nature, so saying chronic at the beginning is not necessary. The "severe" is also unnecessary because MDD is considered the "severe" one, compared to dysthymia. Just so you don't have to type out as much next time.

Aside from that, I'm sorry to hear you're going through a rough time. If you do have treatment resistant depression, then meds may not be helpful. Have you ever considered ECT? I never found it to be a fun experience, but it pulled me out of rock bottom on two different occasions and worked better than any medication I've tried. If it were not for the memory side effects, I'd probably still be doing maintenance treatments to this day. Just something to consider if you ever get to the point of not being functional anymore, as it does work.

Also, do you have a therapist to work through the PTSD symptoms with?
