Bottomed I too am in the UK and know exactly how hard it is to get help and that the advice is always don't stop drinking. That then feeds into our addiction and basically leaves us stuck. I went everywhere to no avail. Eventually I stopped on my own despite what I had been told by the medical services. Hardest thing I have ever done but so worth it and an achievement like no other.
I think you need to find out if you are employed or not. If you're not then you need to apply for benefits and start sorting out some of your debt which will take some pressure off you and help you think more clearly.
I hope you keep posting and asking for support. I remember feeling so lost and alone like you. It can and will get better
