Getting government benefits?

Wondering if anyone here has been able to claim PIP or DLA as a result of their psoriasis. As someone with severe palmoplantar pustular psoriasis I'm pretty much housebound and need help with getting around and basic tasks. For example, I can't walk far and also can't use a conventional wheelchair because of the condition of my hands. Likewise I need help with doing dressings on my feet and I really struggle to prep food etc. My doctor supported me in getting a disabled parking permit but the need for an electric wheelchair when I'm really bad is going to need an adapted vehicle but I'm not currently eligible for Motability or similar schemes. I have to admit I'd never considered I'd be eligible but it's a lifelong condition and I'm actually currently less mobile than a friend who has cerebral palsy and another who is a paraplegic. I was really surprised to get a disabled parking permit and it looks like I'm getting a disabled parking bay too.
