Thanks for using healthcare magic for your queries.
I can understand, whats going in your mind. Even in a single country, there are many sub-cultures and you should always expect some variation in them. You did what was good when you were young and you felt good about it. it was a selfless behaviour. One can always control oneself. Expecting others to behave in the way you want, is now a selfish thing. Only the fact that they are not behaving the way you do, doesnt make them wrong. Please try to understand that its only your behaviour, feeling and emotions are under your control and nothing else. If you dont think so much about these facts, may be you will change your feelings and mood as well. Try getting yourself involved in some hobbies or stuff that you always wanted to do. Spend some time with your family. If these things do not help you, you should seek a Psychiatrist
to discuss these issues in detail.
Hope I am able to solve your queries.
