<human>: Can you summarize the given text in a few sentences?

I'm 27F, father is 60M. Relationship is 27 years old. This is going to be a wall of text. Sorry.

My father and I were very close when I was young. I was definitely daddy's little girl. This started to change when I was about 12 years old. My father was fired from his job twice, partially because of bad judgment due to alcoholism. Both times he was a teacher at a school I was currently attending. Despite how hurtful it was, I grinned and bared it to make him happy.

Around age 14, I became sick. The illness caused absences, which created problems with school. Previously, I had been an excellent student; now I was getting mostly C's. Unfortunately, my symptoms were diagnosed as psychosomatic. My father then became very hard on me, and often criticized me. I was left with the impression that I was feeling sick because I was a bad student.

Fast forward to my early twenties. I discovered that my illness was not psychosomatic, but due to a food allergy (!). I was already working at a job where I was well liked, and started to plow through school after changing my diet. My father never acknowledged any of this. He told me my illness does not explain my behavior, and when I graduated from college he said to me, "About time."

He never compliments me. If anything, it feels like he goes out of his way to question my judgment and subtly insult me. It's gotten to the point where anything he says seems to be a jab at me, and I can't take it. Unfortunately, due to the bad economy I had to move in with my parents, and have decided to get a post-bachelor degree because I can't find a job. Basically, I'm asking for advise on how to stop resenting my father and learn to have a pleasant relationship with him.
