I totally agree that seeing a doctor to get properly diagnosed is the right thing to do. I wonder why you think you have bi-polar disorder? Is this something you have researched? Do mood disorders run in your family? Does the gambling only occur when you feel "manic"? IF IF IF you do have BiP d/o, the right meds will help so much!
Something else you may want to look into is Gambling Anonymous, International. According to their website, they do have meetings in Isreal.

At least you'd have some people to talk to - it's always nice to have people around who understand a bit about what you are going through. The financial pressures would be something they would understand.
