think of africa children who is dying of hunger
realize that if conditions are right, you can die at any
moment
so things like studies, work, whether you pass or fail is really
not very severe things. you must mature more to understand these
things. being mature means that you have know more about emotions.
why people have them and how to control and negate their effect.
being mature also means other things too.
in the short run, you probably feel stress ocaasionally over the
issues you have said. and my advice is not going to produce short
term recovery. but it is not meant to be.
