What do you think the problem here is?

It is not the first time this has happened.. Generally when I quit smoking I get it. Nothing feels quite right, the best way I can describe it is that I feel like I am dreaming. I cant concentrate, I have crazy thoughts, dizziness, cold chills.. Occasionally I feel a bit disoriented (but only occasionally). Its the wierdest feeling and I dont like it! I wish it would go away, have had it for 1 weeks... Please let me know what you think it could be, I dont want to go to a doctor because i would look like an idiot.. "Hello Dr... I feel wierd" LOL i would probably be told to go home and rest. I have researched before, and I think it is Psychosis, obviously only a mild form but I would like another opinion or has anyone had something similar?
