My parents hate me and I am losing my mind?

Neither parent got me anything for Christmas, or my birthday (x-mas eve), not even a card. I don't care about the gifts or material goods at all, it is the feeling that they both really don't love me, don't care about me. I got gifts for them, but this is the last year of that. Both of my parents make a decent amount of money, my dad for example has a yaht, owns his own business etc... My mom is a teacher, so she is not well off by any means, and also she has some mental illness. My parents are divorced. I moved out on my own at 18. They were mad I didn't get a sports scholarship so I paid for myself to go to college. Now I am a professional and I am 28. I went to my dads house recently and there were tubes and tubes of wrapping paper in the living room, indicating other people got christmas gifts. Today, finally, I am having a breakdown and I cannot stop crying in my cube. I am so angry that it is indescribable.
