This is the best decision for you right now, do not listen to anyone who would encourage you to keep trying. You've had enough losses and emotional stress already, the best you can do for yourself is to give you a break. If you ever decide to gamble again, you will be more careful since you've already had a terrible gambling experience before.

The beginners luck is one trap every beginner should beware of. That first win is one big motivation that can ruin the life of any gambler if he is not lucky. It becomes even worse if he does not know how to stop. Gambling is not a must thing, if it is not working anymore or if it is affecting our mental health greatly, we should simply let it go and be at peace with ourselves, instead of chasing and accumulating losses.
