When to walk away? How did you know?

I used to play sites like Bovada and Cafe casino crypto casino sites and I thought after a while they sucked because I played modo and got s couple decent wins but now I'm feeling the complete opposite. I'm happy for the people I see that hit the BIG wins but believing one day I will be that lucky has gone out the window. These sweeps sites have (for me) gotten horrible since about Jan 1st it seems I can't win shit on any of them ever. I believe in luck and bad luck for sure but not as bad as this lol. It's a miracle anymore on any game provider to hit a bonus really or at least one that pays more than . 20 cents or a dollar something. Every time I raise a bet I get murdered, can only win anything on minimum bets then instant losses non stop back to nothing. Based on what I have experienced and the money lost seems like it would be easy to just up and quit lol but for me not so much. I probably have a gambling problem for sure but I manage it well enough to survive and take care of 3 kids. To anyone who has self excluded from this shit and just said to hell with it when did you know it was time to walk away? any advice is appreciated. What has been your experience? I'm curious does anyone feel the same way?I know the responses will vary for sure please no hostility lol.
