Strees to the MAX

I have been trying to be a better person since I found out I was pregnant. I had a high attitude and very strong character. Never let anyone push me around except my mother (that is another story) Since I moved in with my daughters dad. I had tried to be nicer and patient at things. Including mess around the apartment, lack of wanting to pursue a higher education, laziness. But a person can take to much. Just recently, I got very stressed out because I have been holding emotions in. Which I have not done since I lived with my mother. I am very transparent, I say it how it is. Now the reason I have been feeling like this is because on May of this year my mother in law came for a visit since my daughter was being baptize. She came with my bother and sister in law. The lady is 42 and dates a younger men. Her daughter is 19 and has a weird need of attention and complains about life in general. Her son had Down syndrome and is 22. My partner wanted them to stay and live with us which was not a surprise to me bc we had talked about it but did not think then that it will be this hard to handle them two. I mean the mom left back to NY but they stayed. His sister started to work at an Ice cream shop the very week they decided to stay. Now its been 6 Months living with us and they think is Ok to be behaving in a certain way. The teenager brought her bf from NY and stayed in our place. She let him in to their room and slept one night. She does not cook for her bother meaning meals during the day. They expect me to do all the cooking and plus take care of my daughter and work online while they are here. she talks behind my back to my partner and tell her mom in NY that we treat her bad. I talked to her mother today and told her to move here and live here closer to us or come get them bc many awful things have been happening. It is quite a lot to tell but this sure helps me feel better. Now I am relaxed bc I finally told her what I have been holding in so long and happy that they will leave on the 1st of December I feel bad bc they are new family to me, my partners family but he is fed up too just does not want to give in and stop helping his brother and sister. I mean bc their living conditions is horrible in NY
