Hi there!
Welcome to Skincell

Firstly, it seems like you need a

or two.

I went through exactly the same feelings when I was diagnosed. Luckily, my eczema has cleared up now. Your P might do the same.
I'm not exactly sure how Guttate psoriasis works, but I think you're right - it's a condition that is triggered by something else, and removing the trigger may well clear it up. Like any other condition, though, there are other things to consider.
Of course, we're here most of the time, so whenever you want to vent some anger, have a moan, or whatever, there's always someone to listen

Hope things start looking better for you,
Matt.
