When I find myself like that, and I do quite frequently, I come here. I just start reading what other people are experiencing in their lives and try to avoid my own. It seems that I am kinda good at giving advice to others, but when it comes to my situations I draw a blank. It's very discouraging. Others problems make me think about what actions could correct their problems, but when I try to sort mine it's all a jumbled mess in my mind. I lose train of thought, become depressed and question my own personal worth. Repeat. It's a circle to me, but at least when I'm focusing on others problems I don't have the depression beating me down and having suicidal thoughts. There's so many here I can relate to and I try... It's a temporary diversion of sorts, but it's helped me to mask many times. Best of luck to you.
