RoamingMind,
I feel you. I keep telling my mom that the universe is laughing at me. It gives some only to take it away again. It is to a point what when I feel good I am so so afraid and anxious that it will be ripped from me that I cannot enjoy it, which then sends me in another depression. I too do not trust anyone's words; it will get better, this is just a moment, blah blah. Maybe for them these words mean something because it happens to them. How could they understand that even in a hypo state or when I am normal that I am terrified that it will go away, and it does go away, over and over and over again.
I hope that your ability to focus comes back to you. I fear that I am so analytical; able to rip things apart and put them back together as I see fit or concentrate so much on something that it drives me mad. If we could I would give you some of mine and you could give me some of yours. A balance would be nice for a change. Take care!
