Have a serious gambling problem.

I literally have no idea what to do, i can't stop. Im so addicted. Here's the story, i started uni and went to the casino for the first time in freshers, won about 30 quid and was hyped about it. I then somehow over the next few months managed to turn around £300 of my own money into £15,000 both online and in the casino..
I then began losing it all, some days i'd lose around 3k in one day and it is ridiculous. Now, i've lost the £4000 i'd saved from working last summer and am also in debt £2700, so am - £6700 of my own money and the £15000 i won. I just found out you can spend over your overdraft using your card when playing poker this week so have gone way over my overdraft. So now I'm even over my overdraft so probably going to get screwed over with charges.

I hadn't gambled in ages until a week or two ago then started playing poker - bank account was at 0 at this point, but now it's -£2700. I can't afford to do anything, can't afford to go out, can't pay the deposit for my house next year. I have no idea what to do. I really don't feel like i can ask my parents as they always said, don't gamble again, you'll get addicted a few months ago and i always promised them i wasn't doing it when infact i was betting up to £1000 on a single roulette spin in the casino at points..

Any help is greatly appreciated, it's destroying my life.

I've tried banning all my accounts on every site but they let you remove them after 7 days etc.. and there's so many sites it's so easy to find a new one..
