The most important thing to do right now is not do anything stupid (i.e. suicide or loss chasing).  If you don't feel like you can't control yourself, I'm happy to help you timelock your money for the next year to prevent anything stupid.

In 10 years it'll seem like a distant "i really fucked up then" memory, so in the mean time focus on more important things in life. The truth is you just had those bitcoin sitting doing nothing anyway.

But being frank, you obviously have some latent self control issues. You really shouldn't gamble again, or if you do have extremely strict limits you establish for yourself that are not based on loss-chasing. I would strongly advise you don't gamble until you can forget about this loss and consider chasing it.

But seriously, look at al the positive things you got going for you. Your remaining savings are more than 99.9% of the world. Learn from your mistake, forgive yourself and most importantly don't do anything stupid.

P.S. I'd also recommend against casino investing. It's too easy to gamble from there, and it's best to distance yourself from casinos in general when you have a problem.
