Yep, as biohazard said, speak to stepchange, and be honest with them. They’re a charity organisation so don’t get any payment for what they do, simply just want to help you.
They’ll work out all of your finances, even to the point of saying you spend £100 per month on going out to socialise. They understand that spending all of your spare money paying debts off is the wrong way to go, because if you can’t at least enjoy yourself a little it’ll put you in a bad frame of mind, an unhappy place, which is the worst place to be for anyone who has or does suffer with any kind of addiction.
Also, finding some sort of hobby or interest to fill the time. I personally chose to volunteer at a charity and do some exercise. Made a lot of new friends doing it and for the most part took my mind off other things that bothered me or got me down at times.
Don’t dwell on it too much, you’ve done incredibly so far, paid a huge chunk off in a short amount of time. Get some help with the rest and go easy on yourself! Always people here to talk to or ask for advice if you need it pal.
