No thanksgiving

I moved out of my parents house about 2 years ago. Since then, i barely ever see them. They NEVER call/text me! I'm always the one calling them, texting them, trying to make dinner plans with them. And they NEVER answer thier phones or respond to texts. Yesterday, my mom said she would be at my house within 30 minutes. Instead, I sat there waiting for her for 3.5 HOURS! Calling over and over with no answer. Then when we finally got to thier house, everybody left me there alone for 3 MORE HOURS waiting to have 'family dinner'. At this point I was so fed up that I just had mom give me a ride back to my house and didn't even have dinner. On the drive, we got into a huge fight and I told her I wouldn't be coming home for thanksgiving. I just feel like I shouldn't have to TRY this hard to be a part of my own family. If they don't want to spend time with me then fine, they get thier wish. I'm having a frozen pizza alone for thanksgiving tonight.
