Hey josh, that’s good to hear you have loved ones willing you to succeed.
First step I would take is make an appointment with the citezans advice bureau. They can help put you in contact with debt consolidation experts and charities who can help.
I would also check out:

And read this article for ideas:
Reach out to citizens advice and look up gambling debt charities in the uk to help further.
You are 22 so I would persume too young to file bancrupcy, but with help from these charities some of your debt could be written off and they will help you get a loan that will consolidate your debt so you only pay one payment back to the loan provider.
Let me know how you get on and good luck! 🙂
