Haven't gone through it personally, since moving half way across the country ended up actually making my depression a lot better. I didnt realize how toxic that place was. In any event, Ive looked into it some. Its really not that bad or scary. While I can't give you firsthand knowledge, theres one thing above all else you should know: You know how sometimes in fictional movies or on TV, they show ECT?
Its nothing like that. Nothing. Infact its basically the exact opposite of that.
