For me? Yeah, I blame myself a lot too, maybe even too much.
Well it depends on what you blame yourself for,
do you blame yourself for loosing too much?
Not cashing out soon enough or even at all?
Spending too much time on the casino?
Encroaching on your productivity time with your gambling activities?
Adding much games to your betslip because of greed or missing out on wins because you neglected a game due to its low payout?
There are many things to blame yourself for and I would add that instead of blaming yourself for all those stuffs, just learn your lessons and move on.
The last time I felt that bad was few weeks ago three games were dropped on a group and I neglected the smallest odds ticket because it wasn't enticing and guess what!, I lost a very sweet 6 odds because of greed. I was not happy at all when I saw the results at all.
