Welcome to the boards. I dunno what psoriasis is, but I'm sure someone on the boards will recognize it.

Ihope coming here will help. I'm sorry about your mom - what's shes done to you, everything. Don't blame yourself for what happened - you didn't ask for any of it. I don't think you need to take blame for it - it just happened.

It sounds like you're having a rough time right now... keep going, you've made it through so much aready loads of hugs and keep posting
