Hi Danielle and welcome.
Well done on looking for help. If you read the other stories here you will see that you are not alone with this problem. You will also see the success stories, what are they doing that you can apply to your own situation?
You will see that many people put put barriers in place. How about a blocker to stop that online gambling? How about being completely accountabel for any money so that you can’t gamble secretly? Maybe limit your access to funds entirely for a while.
Use all the support you can as well. keep posting here, get to the groups if you can. Think about other support as well; places like Gamblers Anonymous.
Whether you get that loan or not you need to look at the finances. Are they manageable? Can you kepe up repayments in a sustainable way? if not then get proper advice. Lots of financial options around these days, from bankruptcy through to reapymant plans with a lot in betwee.
Keep posting and let us know what positive steps you are taking.
