struggling to sleep :(

hello everyone, my name is lucie and I am 20! I have had psoriasis on and off for a few years but recently I got a massive flare of guttate psoriasis on my back after a bad sunburn. I also have plaque psoriasis in my scalp which I have been struggling to medicate just because I have curly hair and getting the creams in there is really difficult :( I've been struggling to sleep a lot recently just because of the irritation on my back, it's so itchy and can be painful when I move in certain ways. I feel like I should be enjoying my experiences at university more but I'm always a little self conscious especially because I have patches on my face as well and covering it with makeup is really difficult because it just flakes off. Some days I feel completely okay about it but other days I don't want to leave the house because I am shedding skin EVERYWHERE, I wake up in the morning and my bed is covered in little flakes :( my hair is one of my favourite parts of my appearance and now I'm always aware that I have awful dandruff due to my condition. I don't know what I'm looking for here I suppose but I've been reading lots of other people's posts and it's nice to know I'm not alone
