I've never posted on these sites before. I recently had surgery and they found endometriosis all over my left ovary and behind it, after months of back pain and feeling sick. I also started the prostab treatment but I'm having side effects: mainly sudden on set of depression. It's like someone switches off something in my brain. I can hardly bring myself to talk. I just feel so alone. And that no one really understands. Does anyone get this? Such sudden lows?
