Well, I did say that you didn't have to answer if you didn't want to
I already had a hunch that it was because you had previous big wins on the game. All of us have chased that dragon, not to this extent I think/hope, and it rarely ends well. A couple of years ago I won almost 5k on Bonanza and managed to give all of that back in a span of weeks. I haven't made that mistake since and moved on from Bonanza, I give it a couple of spins now and again but I used to play it almost exclusively.
The only advice we can give here is to exclude yourself from all casinos and don't spend that last bit of money that you have saved. You're never going to get back the 100k you lost on Gonzo by playing Gonzo.
