Help pls, I'm freaking out!!

I was healthy and fine until I decided to lose weight (lost 60lbs in 6 months). I did Keto and IF, and my skin was fine, until I began to develop psoraisis,confirmed when spoke to my family doctor and using a prescribed cream.

Now I'm looking up info on it and am so sad/scared, there is no cure so I ruined my body essentially. I'm honestly freaking out. Is there anybody who has it and has any solutions/remedies to make the scarring and redness disappear?
