I cry myself to sleep.

Nothing much just have a mental breakdown

I read one of Um_nik's blog, he said something like if you are stuck on a problem, you should try it after a while (few days or weeks or months), cuz if you keep on trying you'll keep on thinking in the same way. So that's what I follow, if I'm stuck on a problem for like an hour or two, I move on and come back after a few days to give it a try.

To be honest I just look at the editorial (this is why I'm green)

Keep the problem in back of your mind and keep thinking and do some other things

Keep the problem in back of your mind until you find yourself stuck to same thing again and again

Or ...

I give it a break and try to solve next day or see the solution for approach and try to code.
