I've raised £300 to Help with rent and bills while I appeal my PIP refusal

I have suffered from Fibromyalgia and ME for several years and my condition is getting worse everyday. I've recently been refused for the 3rd time for disability benefit despite having time off of work every single week for the last 6 months or so. I was hopeful and relying on being accepted for benefits this time around as my condition had got much worse since my last application.
I have exhausted all pain management medication available and none do anything to help my pain and stiffness levels. I am currently awaiting a referral to a rheumatologist and the pain clinic but in the mean time I am left with no pain medication meaning that I am taking time off of work every single week with no sick pay and therefore do not make enough to cover my rent each month.
I never wanted to have to set something like this up and ask strangers for their assistance but it's reached a point where if I don't do this, I'm not going to be able to afford rent and bills along with the thousands of pounds worth of debt I have accumulated through having to borrow money due to barely being able to make it to work.
Any and every penny will help me stay on my feet until I can appeal my benefit rejection and I thank you all in advance for any help you can provide me.
