Basically, I have no close relatives, I only have my younger brother who depends on me so much and to what I know I must not fail him.
I can't say that I understand how you feel, cos I'm not in your shoes and each of us encounter this "Family Matters" in completely different ways, each person has their own specific feelings on this "Family Matters", but I have more or less almost the same family you've got there or mine is worst.
My relatives (since my parents divorced, 2 of my relative moved in to take care of us) never ever gave us a compliment, no appreciation, Psychology Abuse, military disciplinary, money issue involved, etc.
I was so mentally tortured, everything I've done they never seem to like it, even to the persons who I'm dating with they don't like him either.
And always scold us with no apparent reasons, and always with mocking that we're good for nothing.
We've tried to please them, but seems that they are no pleased.
So I think and think, this is not a FAMILY DEFINITION, where a real family would stick together and go through things together and understands each other, say thank you to each other, not compelling each other in order to have their "wants" satisfied.
And I make a real big turn on myself, I've decided to move on with my own self, I "deserted that kind of family", and I'm happy with myself.
Now I have my own "family" (and they still don't like my life partner) and I will make sure, whatever my "that kind of family" did to me, I won't and NEVER EVER repeat their mistakes. Because I know that "family" this word gives a HUGE impact on children of mine later.
But as a Daughter, I won't forget what they had given to me, I will still act according to my responsibility.
So whenever you, any of you saying "my family is like this and that", just "desert" them and go on with your life, nobody lives forever, you can't please everybody, just please whoever appreciate you.
Be responsible on yourself, love yourself more but not too much.
