I'm ging through work frustrations too, and it helps me to journal about it, especially the things that are the most frustrating. Depending on your particular situation, it could be this one thing you can't seem to remember, or you blank out in situations that you used to know instantly....I donno. Your boss can have a positive or negitive impact as well, I hope he or she is support, becuase yalling at you about deadlines never helps either.

Whatever your going through, it's gotta be taxing to feel like your at your wits end with it all. I donno, I think talking/writing about it will help though, it sucks having to hold that much frustration in. I'm glad you wrote about what you're going through.

Take care.
