joesimon, keep in there, the 2nd line treatments available from the dermatologists are very good, and usually make a difference to most people with your complaint.
Sorry about the 8 month wait, we're trying to do something about that, in the mean time, carry on with the 1st line treatments from your GP, he or she has many treatment options, I'm not sure whether or not you have exhausted all the options.
Your condition is very treatable, but sometimes its a matter of time before finding the right treatment for you.
Private treatment is an option, but be wary that the 2nd line treatments available from the dernmatologists sometimes require ongoing "follow up" (blood tests etc).
Good luck.
PS couldn't find anything in the original post that suggested clinical depression Aero, he sounds more pi
d off than anything, but of course your absolutely correct, seek help if feeling that bad.
