i feel terrible

I have this AWFUL migraine that won't leave. It started last night about 6 pm and I thought I had it under control but I guess not. I woke up with it still. Now my vision is getting blurred and I don't feel so good. It is taking all I have to just sit here and look at the screen. I have to do something to keep busy or I believe my head will explode. I have some Paracetamol active fast in my purse but if I take that I will have to go home and sleep. but i still have to attend my class.. huhuhuhu
