I think I can pass as a compulsive gambler based on your description, After some regrets and realization, I got decided to reduce my activity and start changing myself. I've been a gambling addict for years and wasting countless money on my addictiveness. Friends and foes tried to change me before but I can't stop being the same, It's hard to get rid of being a compulsive gambler but it is possible. Try slowing down the activities and putting a limitation on yourself. It's almost a year since I start to change and it brings a significant change to my life. I also didn't seek professional help for my addiction. Just some deep realization I was able to change.
Changing is not impossible.
Changing is indeed not impossible if you are really willing to change. If you are already a compulsive gambler it would be very hard to stop in a snap because gambling is already in your system and that you dont have the ability to control it and you dont care about the people around you. In this case, the only person that can truly help is your own self, if you will be determined enough to stop being that person then you can, you dont have to stop immediately but you have to stop little by little until such time youll be a able to better control you gambling habits.
