Hi Sadley, sorry you have a struggle with depression. ECT can make a big difference with some people I know. It does interfere with work so it might be looking at a lower deductible plan for next year and saving a good nest egg so you can take off enough time to go through the ECT sequence that is often 3 days a week for 2 weeks or longer. Then depending on outcome they will recommend periodic ECT.

I am sorry you are having a difficult relationship. Many times partners with depression have suffered emotional or other abuse long before you knew them. These can be a serious impediment to intimacy. Ever thought of a counselor for both of you and your relationship?
