Help me please, psorasis or eczema what is it

My body is covered. It burns it’s so itchy. It looks different on my arms to what it does on my hands. It’s so so so much worse in real life. Does anyone have any advice or can anyone tell me what it is. Ive got an appointment to speak to my GP, they’ve not been great so far. I’ve purchased every over the counter creams and ointment possible and noting works. I’m a healthcare assistant to the constant PPE isn’t helping, I’ve recently returned to work from mat leave and I had this before so it’s not a glove allergy. ANY help or advice please I just need some help :(
