Skin Irritation - Trying to Find Unbleached Toilet Paper in UK

Hello everyone, I've been suffering from a constant irritated vulva for about 7 years now with no help from doctors... Been wasting so much money and time, on tons of medication for YI and other stuff for years which didn't help at all. In a lot of pain right now and at the end of my wits. Only recently found out it's probably dermatitis and reddit's been more help than any doctor or clinic and I am so grateful.

I'm currently trying to find a detergent and toilet paper that might help with my skin irritation. Found out that baking soda is a wonderful replacement to detergent, however still stuck with the toilet paper. I live in West London and can't seem to find Seventh Generation (which I saw mentioned on a lot of pages) anywhere. I've tried cheekypanda and ecoleaf from amazon, some other brands and they sound 'eco' but they're bleached as well and I still feel horrible... I will be so grateful if anyone can give me a suggestion on the toilet paper, and if you know anything about the irritation as well. Hope this wasn't the wrong place to write this post. Felt quite embarrassed to go on r/unitedkingdom to mention my irritated vulva among the sea of political posts..

Thanks in advance. and hope you have a good day.

Edit: I want to mention something that's really helped me and never see mentioned anywhere. I use a piece of cotton and gauze swab instead of tampons or pads. You can get them anywhere, I order gauze online. Feels wonderful, so soft and breathable, and you can place a pad under if you have heavy flow just in case. Pads were aggravating my skin horribly, and I feel much better during periods which makes me think something must be wrong with my detergents for sure.
