"The job of a parents is to raise their children till the children can survive on their own." Looking at it in this light, your father did his job and well you did yours. I raised my daughter on my own and it wasn't easy and boy did I make mistakes. At least we know we did, where as many a parent hasn't a clue. Most likely finding money on their own to go to school will make them stronger people.
Our old people are being poisoned by the doc, big farm and big pharm, it is making them crazy. If they were unstable to begin with all this is really making them nuts. Have pity. Have a good rest of your life. Everybody has eatting disorders, to much, to little, stress over what to eat. So you are normal, now do you feel any better. If not do you know how hard it is to find a good man at your age. kiss him before someone else does.
