Need to vent!!!!

I have a relative that lives with my family. He makes comments to my 5 year old and 2 year old like "oh, mommy's just fat!" Etc. Tonight I went for a second serving of dinner since I had a really small portion the first time and when everyone ate the appetizer I didnt since this particular person sneezed chunks all over my floor (I'm a germ-a-phobe and a weak stomach ). Well he turns around and yells you're having another piece?!?! I'm wanted to throat punch him so badly. I have only gained a little over 4 lbs and I'm 22 weeks. I also have thyroid disease with nodules. Ugh!!!!! So sick of it, so ready for him to move out. End rant.
