unreal

I am feeling so disconnected and sick. I can't stop shaking. I have been awake since one in the morning, just couldn't get back to sleep...I want to leave work so badly, but I know I have to try to stick it out. I don't know what I am doing here. I am so confused. This is so hard to deal with.I just don't know what to do next. I can't stand up, I am afraid I will faint. Panic attack is coming on.
