Hi Jay,
I would agree with Ican, if your family hated you then they would be no longer with you, after all they have plenty of reasons to leave if they wanted to.
I’m sure they will have heard all the words and promises before; now you should show them by your actions how much you really want to stop.
There is a lot of gambling around these days, the good news is that there is also a lot of support available. Take a look at the resource link here; you will see there is a lot of support in your country. get to a local Gamblers Anonymous meeting if you can. As well as helping you stop gambling you are also bound to meet others with past financial problems, find out what they did to address those problems.
Keep posting and let us know what positive steps you are taking.
