Is it weird that studying helps me cope?

I was crying a bit earlier because I was feeling sad and pathetic. I don't know why, but I sometimes I have these weird episodes that I feel depressed and have low self-esteem and feel unfulfilled. But then I started studying in my textbook and it temporarily took my mind off, which made me feel a bit better, but I once I start crying, it's hard to stop.
What are some of your coping mechanisms?
