Hey OP,
You are going to be okay!!!
I sometimes take a look at the personal finance boards on reddit and they are full of people who have gone from large amounts of debt (tens and tens of thousands of pounds) to in the clear. I got in a bit of debt in my early career (Approx. £5-6K). So, don't feel bad, you are not alone.
Is all of your debt with one provider? If not, make a list of all your debts. How much you have with each provider and what interest is being charged.
Then, take a look at "Snowballing" vs "Avalanching" methods of debt clearance which can help you tackle debts in the most cost effective way. Pick whatever you feel most comfortable with. Essentially, you make minimum repayments on all of your debts bar one. Put all your spare money into that one to really target clearing it. Once that is cleared, you'll have extra cash to target the next debt.
Remember, once you've cleared some debt, you may be eligible to open a 0% credit card. This could give you a bit more breathing space to transfer some high interest debt, and gives you more money each month to throw into clearing it.
If you cannot keep up with minimum repayments at all, contact step change for advice. They will go through your options with you.
Often it's acknowledging that you have a problem is the most uncomfortable stage. The rest won't feel so bad as you're taking positive steps to tackle the issue.
