In Jan 2010 I started ECTs 3x week for 6 weeks. Yeah, those "memories" from those weeks are VERY blurry, so just make sure yoou don't have a baby or get married-LOL!!! My husband was thrilled, he said "I finally got my wife back" . Alas, it did not last but 3 months, but that is me. Everyoneis different.
As to people with depression having good and bad days, I haven't had what I consider a happy day in the standard sense of the word since 2005.The dog does something really stupid and funny, my daughter snuggles with me aand I smell her shampoo, beautiful spring wildflowers. Intellectually, my brain says these should cause you joy and so I smile and go along but I still feel like an empty vessel, dark and bottomless. BUT I had 3 great months after ects which I would not trade for anything, so I know that JOY can be achieved. Don't fall for the stigma, they are completely safe, you are under anesthesia and it is totally worth a try. Major Depression is an illness so seek avenues that may help, wherever you find them (within reason) Good luck!
