Yeah, I have struggled at times with it as well, it's not easy to talk about even if you know you should. I always find it's hard to even place where to begin, and how I have even gotten there. The thing that always struck me about when I really had it wasn't so much being sad, I don't think I was ever really sad, I just felt hollow, worthless, stuck, listless. It felt more like on the first blush I had no emotion anymore, and when I tried to dig deeper it was an ocean of turmoil.
