This is a nice and precise advice for those who are facing the aftermath of losing in gambling.
Accepting the loss is the no. 1 should be the one to do, move on so that you can't be eaten by your own emotions that can cause more psychological damage. Socializing is key too, talk to your family, talk to your friends and find some icebreaker that will lift that heavy thing on your mind.
Don't be depressed, you gamble in the first place that's why you should know the risks first, don't chase the wins. It's not a wise thing to do.
