Hi David,
Well done on posting here when you are struggling.
Try not to just “…. see how long I last….” though. You are aware you are vulnerable so use that awareness.
Who could you give your money to so you can’t gamble it? Where would you gamble? Ban/block yourself from it.
Try not to look at those “missed chances”. Certainly don’t look at odds etc. if watching sport at the moment is making things hard for you then don’t watch it right now. We all had our wins, they make no difference in the end as we just carry on till we lose.
Keep posting and let us know what positive steps you are taking to make that next bet harder to place.
