If you feel unsafe with the casino site where you are playing, don't ever play there. If you have spent a lot of money there, then forget it, don't think about chasing it and getting it back. Just look for a site that makes you feel safe.
The casino will not hypnotize you to spend more of your money in the game if you have control and your limits. I know being trapped in an addiction is uncomfortable. but you already know the risks from the start in casino games. calm yourself and recover your finances gradually. Avoid all forms of gambling first. I'm sure you can do it.
