You are not alone. Many of us have it too, just that we don't want to think about our familial probs so that we can continue to do other things more important than wallow in self-pity.
Some had it worse than you, some were raped by their own family members, some have been beaten up by own family members but they didn't tell anyone because we are all allowed to put behind our sorrows and move on, here is an alternate place of the universe where EVERYONE (well, one of them is me) escapes from the real world which is plaguing us with anything.
