Recently i've given up smoking and drinking and over the last couple of weeks i've been feeling strange and i'm getting scared. I don't feel right i get all anxious and i feel really queasy. I don't seems to be real and my head seems fuzzy. I'm tired all the time even when i've had lots of sleep. I know it sounds silly but i can't help feeling that i'm really ill but when my mind is active like now when i'm on the computer i don't seem to feel so worried or strange. Can anyone tell me if this sounds a little like having a panic attack or not. Please i am scared.
