I am too much emotional. And I can't control it.in my life I trusted many persons but they betrayed me.in my childhood I lost my brother.my mother is always tensed about me.I don't have any freedom.for that reason I can't sleep.always I think that how can I make them happy.I am only 20 years old.so what can I do?

Stop worry about how to make them happy. You need to worry about how to make yourself happy.
