Decide and take some action if you are really dedicated on quitting gambling, if you are just going to ask some advice but you're not going to apply it, then it is all useless. Quitting gambling might be a tough task to do but we have to, the consequences that we are going to face if we are going to continue is much worst.
You could also ask for help to your friends, they might gives you a little help or to your family.
Asking help from someone else might not do. We must stop this bad habit starting from ourselves. If we can stop it right from ourselves then we will be able to get out of it much quicker than we expected. Sometimes it might not be as instant as we think but it is for the best so it is better to do it and start from ourselves
On the contrary it is better to ask someone who is knowledgeable about the case on how to improve one's control on gambling. Often times the case of being addicted cannot be solved alone. The person needs to undergo rehabilitation and withdrawal syndrome. And once the person is in that stage he needs to be taken care and guided by a person who is qualified to that job. Though I agree that this should begin in one's self.
