Time To Move On???

It's 5:37, and I've not slept a wink. Yesterday afternoon, I had yet another argument with my mother. She cooked on thursday. Yesterday, I took a pack of chicken thighs out of the freezer to defrost. At 4 p.m., I was about to get dinner started. She asked me what was I planning to cook, and I said that I wasn't sure. So she suggested pork chops. I told her that I had already defrosted the chicken thighs.She said "we'll be flying soon, from eating so much chicken. My sister had done boiled boneless chicken breasts on Monday with some milk sauce. I was gonna let the comment slide, but just couldn't stop myself. So I asked her why does she always have to criticize everything. And she says "all I did was make a comment" And I told her that I was sick of it 'cause all that comes out of her mouth is criticism and negativity. She always has something to say, without thinking about how it will affect a person. My mother is really toxic. So basically I told her that I was making Baked Brown Rice and steamed chicken thighs and to let me cook in peace. I said " you can eat it or not, it really doesn't matter to me one way or the other! She had the nerve to say that I need a Psychiatrist. And I told her that if I need one, then she needs a better one. She always try to make it seem like I'm paranoid and twisted in my way of reasoning & thinking. But, I've talked things over with my fiance & closest friends and they all seem to agree with me. About 30 mins. later she left the apt. I could care less. She returned during the early evening. We haven't talked since then. I have made a decision. At the end of the summer, I will move back to Pennsylvania. I have to do it because I need to move out, but the rent here in New York is too damn high. I refuse to pay $800/mo. to live in a rented room with my son & fiance. For much less than that, I can rent a decent 2-bedroom apt. in Pa. My fiance already spoke with his best friend in Pa., to help us look for an apt. Now, I have to save as much money as I can. It's a perfect excuse to spend less $$$ on food. LOL I told my 8-yr. old that we would be moving back to Pa., and he does not like the idea. He wants to stay here in N.Y., 'cause all of our family is here. It's so sad. He just doesn't realize all the stress that Grandma is causing his Mommy.
