Don't quit cold turkey, that'll just make it harder. Instead, limit yourself to how much money you can lose, and gradually get lower. Make sure you discipline yourself so that when you get to your limit you don't start saying "just one more game and then i'll stop..." etc.
Another way is to find another addiction, a healthy one ;)

Have you tried blackjack instead?

I have had a gambling problem in the past. It was hell. In my case I kept trying to stop on my own, but kept going back to it. It really was an expensive nightmare that took every penny I had. In the end I knew I needed help to break the cylce, a bit like a smoker who has to get over the first weeks or months.

I am in London. I did two things. Gamblers Anonymous, which to be honest I found pretty primitive, but it didn't matter as it was a place which represented my commitment to stopping. The greater thing that helped me was counselling with Gamcare (.org, .com, can't remember which), this again was only a place to help keep my commitment going, but was more enlightened that gamblers anonymous.

The first stage is an absolute clean break from gambling, close all the accounts, stop chasing your losses, forget stopping after the next win. Make a commitment never to gamble again and go and get support.

Poker like any gambling can get to be an addiction if you let it.
The only way to get help is therapy or joining a Gamblers Annonomous Group. They have those on line and in most areas.
You need to stop now. You are too young to waste money on games of chance. Those that can not control it need to stay away from it.

The Poker sites online are the Worst. Take it from someone who has played POKER for 25 year.
When I play in a real Poker Room at the Casinos here I can win fairly regular. When I play online I lose most of the time.
Although you are playing the same game it is totally different.
You are playing faster, many more hands per hour than you would ever get to play LIVE.
This is for the HOUSE the ones who own the online site. They take a rake and the faster you play the more money they make.
The honest truth is NO ONE online really wins regularly. It is almost impossible. Money is disappearing but it goes to the HOUSE.
If I play online I play the lowest amount .25/.50. Just for the fun. If I lose more than $5.00 I quit. Sounds funny but I dont like giving my money to the HOUSE.

When I play in the Casinos I play $3/$6 or $4/$8 and sometimes higher. But it is real not like online. I know I have a chance of winning $100-$200 when I play and over time that adds up.

No one gets RICH playing Poker. The Pros you see on TV lost lots of money over their careers. They dont really make money at Poker it is the advertisements they get hired for.
These Pro can pay $10,000 for one tournament. And even more. If they don't win and there is 5,000 entrants they lost their money. Happens all the time.

Here in Nevada where I live we have a saying for those that can't walk away "the lost their house on the game". And it really happens all the time. In Vegas you see those that hock their car, their home and almost their kids to PLAY and gamble.
Some go through half a million and now are living on the streets and at the soup kitchen.

Dont let this be YOU.

If you can not control it you must quit. If you learn to control it you can do like I do and learn the game inside and out and then play to win.

And get off those internet sites, they will ROB you blind.

Good Luck

You need help and I would suggest you don't try to fix this problem alone.

Take a look at the 'addiction advice' resources here:

Gamcare and Gamblers Anonymous are both there to help you.

OK first of all stop panicking you must enjoy the game as well to keep playing .. i did the same when i started last year lost about the same over 6 weeks or so . i went to the library read some books and improved my game im now up over £3k in 1year so its not all doom and gloom i would suggest you get your accounts down to only 2. people think if there doing b ad on one site they try another it don't make any differecne its the same game where ever you play all on line sites run of the same random generater so moving to another site really is no point stick to one and put a limit on your deposit account . and don't break it try to make it last . OK my advice is to play sit and gos only to build up a stake to get you in a tournament then you are basically free-rolling keep an eye on the runners most site s say 45 in will only pay top 5 but 51 will pay top 10 keep an eye on this and when you play watch the blind clock waste your 30 seconds if it means the big blind gos up on some body else .... learn to play better and only put in a certain amount each week and if you get a good win cash it out and start again don't play re-buys its a lottery on line for the 1st hour so only play freeze outs ........ OK no good gamble anonymous then......good luck and dont over play if ya tierd come back tomorrow it will still be there play when you feel at ya best when you just had a shower
