Hi Siccy,
I doubt your family would be better off without you.
So put that out of your head
My guess is that if any family member in any family gets a long term medical problem it alters everyones lives. That's why we are families.
I am not married and have no kids but I can say it's frustrating and embarassing to have to ask my parents and brother for help. It's no fun watching your 60+ year old Mom carry things and debating whether you want to risk a flare up or more intense pain.
Be thankful you have your husband and daughter, go see that doctor and try to keep moving on.
