There was a period, like 12-13 years ago, where I betted every night until 3 -4 am and placed random bets on live matches from like Poland and most of the times on sports where I don't really know a lot of it lol. Biggest tilt moment was when I kept on loosing and loosing and decided to go all -in (on a tennismatch of V. Williams). Luckily won my bet and realized it could have ended really bad so stopped gambling. Started getting active again a couple of years ago but just with very low amounts for fun and excitement.
This is what happened on most of the gambler being bust but in your case you got lucky on your final bet. I believe I have this kind of experienced too. I always bet very careful at beginning using small amount and when lose streak hits me hard then I always all in despite I just lose approximately 30% of my bankroll. This is how the typical human behave towards continuous lose. We are being pressured to place huge bets just to recover quickly without thinking how much we are betting.
We only feel the fear right after the all-in bet. I believe this is what happened to you. The chills when you think what will gonna happened to you in case your last bet lose is crazy.
