Hi TSL,
I hope you are feeling better that so many people here care about you and took the time to reply. Gambling addiction is a complex problem that build up over time so there is no easy and quick solution but still many people have overcome it and lead the good life.
Ultimately only you have to decide that enough is enough. I hate to be the messenger of not so good news on the job market. It is a known fact that companies nowadays prefer to hire younger people because they cost far less than someone with experience. I think even a part time or completely different job will be good if it take your mind off gambling.
