Debt help appreciated

LJLJLJLLL

Hi everyone, ive never really done this before so im new to it all. Basically i had a big win on the slots a couple of year back but it actually backfired as i came a bit addicted and didnt track my money to the point i didnt have enough to pay my bills. I took a loan out and then that loan became another loan and then another and so on. Anyway long story short, ive got 2 loans (1 of £5000 but the interest rate on it is extortianate so i still have £7000 to pay and havent even touched the loan bit yet. Im paying around £325 a month and it will take 2 years approx to pay off. The other is £2000 but thats low interest and im happy with that one as will be gone in no time. Im comfortable paying it and have managed to get myself okay woth money but it just annoys me as i want to save for a house. Just wondering has anyone any advice regardingthe high interest one because i would love to pay it off quicker and its annoying as i know its the interest which is making it take longer.
Any help is appreciated
