I am sorry you are going through this. I can relate.
I have treatment-resistant depression and am now trying stimulants. More specifically, I am taking generic Adderall, along with citalopram, Wellbutrin and low-dose generic Abilify.
I have been taking lower doses of Adderall for awhile. I am now getting into higher doses and feel I may be getting a positive effect. This is the third day of the higher doses. Have you tried stimulants?
If this does not work, I need to consider ECT.
I hope you find some relief soon.
Love to All.
