Useless

So it's been a pretty bad week for me. Just like my anxiety has been acting up, my depression is also acting up, and last Friday I got hit in the face with a ball with resulted in a mild concussion. I am now mad at myself cause I can barely do the things that were normal for me, almost passing out on Monday at dance, having to skip karate entirely on Tuesday, Wednesday I just sat the entire time at dance, and Thursday I was doing ok at dance then I almost collapsed while doing a turn. I can barely keep my balance, I'm shaky, and I can't preform to my fullest extent. It makes me feel useless, weak............... and even more broken then I already am.
