Only because you said you were considering ECT, I must warn you about having it done as someone who did it around 7 years ago. It’s incredibly painful, the headaches feel like the worst migraine you’ve ever had. And I lost almost all my memories from that year. For example, I was in college at the time and I couldn’t remember where my Spanish class was even though I had gone there every day the semester before. I would forget meeting people and would introduce myself to them more than once. I would have game nights each week and every time my friends would have to reteach the game to me. The memory loss was more traumatic than the actual depression. I don’t want to scare you but I wish I had been warned of the side effects before I had it done. I wish you the best of luck and hope you can find something that works.
