Expectations from life, family, marriage and friends are normal.
What is not normal is how much you expect. If you expect too much, you will be disappointed. That’s life. Its not fair and people aren’t perfect…human beings by definition are imperfect.
What you could do is take a holiday…go on vacation to regroup your thoughts. When I reach a dead-end, I get away from everyone just to think about what I need to do next and what my attitude/expectations should be. Try to get some counseling so you can at least talk these issues out with someone who can help you make sense of them. Find a hobby or start to support a cause actively. We spend a good bit of our lives trying to get somewhere professionally. But what happens once you’re there?
