Hi ~ I'm sorry you're having such trouble.
Have you gone into therapy? I know you said you're trying lifestyle changes, but have you really had therapy? By that, I mean gone into your past, and studied what may be causing your depression? Therapy can be very helpful, and can ease the depression alot if not wipe it out completely! Alot depends on the person and the causes of depression.
I urge you to at least try therapy. And if it doesn't work, try medication. Not ALL medication effects your liver!!! Plus you should NEVER abruptly stop the medications -- you must wean off them, with the knowledge of your doctor. It can be v
ery dangerous to just STOP the medication quickly.
I wish you the very best. Please let us know how you do. God bless and please take care. Hugs, Lee
