That's because your request is much too specific. I can give you some generic 'family troubles' quotes, but they probably won't seem as directly relevant to your own situation as you hoped. As Tolstoy said, "Happy families are all alike, while every unhappy family is unhappy in its own way."
They say that blood is thicker than water. Maybe that's why we battle our own with more energy and gusto than we would ever expend on strangers.
People talk about “dysfunctional” families; I've never seen any other kind.
Family quarrels have a total bitterness unmatched by others. Yet it sometimes happens that they also have a kind of tang, a pleasantness beneath the unpleasantness, based on the tacit understanding that this is not for keeps; that any limb you climb out on will still be there later for you to climb back.
~Mignon McLaughlin, The Neurotic's Notebook
Are you under the impression that family's supposed to make you feel good? Bake you an apple pie, maybe? They're supposed to make you miserable! That's why they're family.
~From the T.V. show "Supernatural"
I believe there is a fine line between love and hate, and that line is family.
We cannot destroy kindred: our chains stretch a little sometimes, but they never break.
~Marquise de Sévigné
The thing about family disasters is that you never have to wait long before the next one puts the previous one into perspective. ~Robert Brault
When our relatives are at home, we have to think of all their good points or it would be impossible to endure them.
~George Bernard Shaw
Family quarrels are bitter things. They don't go by any rules. They're not like aches or wounds; they're more like splits in the skin that won't heal because there's not enough material.
~F. Scott Fitzgerald
Family is just accident.... They don't mean to get on your nerves. They don't even mean to be your family, they just are.
Blood may be thicker than water, but so is a milkshake, and you don't see me granting permanent loyalty to my local diner.
