You will need to get some professional help because I do not really know how to get someone to with with gambling.
That person is going to guide you and you should approach it the best way.
yeah it's a good idea to go to a psychiatrist. you might meet and face to face several times and perhaps you also have to pay the costs, but I think the best doctor is yourself. because you knew what happened to you. you have to get out of gambling. you must have a commitment to this
