Everthing is just getting weirder and worse. I went to the doctors on Thursday and explained the problems I've had, and she decided to change my meds from 40mg citalopram to 75 venlafaxine. I got to do a week on 20 of citalopram before changing over tho. Well. Today, I was in very high spirits. Very unusual. Happy, whistling, and even singing while at work. I was like that for a good few hours until having a conversation with a friend at work, and he totally unknowingly and innocently made a comment that sent me straight back down into the depth of depression again. It was instant though!!! But after the conversation and when I'd got back to working it's hard to explain, but I wanted to be happy and sing again but at the same time I was feeling really low and having bad thoughts and almost crying. Does any of this make any sense to anyone? Also does anyone have any experience to share of venlafaxine?
