whats up w/ me?
If you are stressing about many things, and if you often find yourself crying over trivial stuff then this is all on your nervous basis. You will have to find a way to balance these emotions in order they don’t affect your physical health.
Have you been always like this or just recently? Are you male or female? And how old are you?
This also might be connected with hormonal changes in the body. Sometimes it is a good thing to change a diet. Try to bring something new in to your body. As I can see you have no problems with sleeping which is a good thing.
Did you have any medical problems before this?
All the best,
