I feel that my mom is acting annoyed towards me, what is going on? (Long question description)?

When I was little I didn't really have a good relationship with my mom. She was very strict and didn't show much love towards me when I was growing up. That is until I was diagnosed with schizophrenia. We started going to therapy sessions and the doctor recommended that my mom should show more love towards me to help me progress more. Well she started caring and paying attention to me now, and I still felt a little uncomfortable since I expected her to start screaming the same things like, "your stupid!" or "you good for nothing human!" The thing is she started to actually try not to get angry easily if I made a mistake, so I was wining my trust back in her. We then attained this relationship that I never knew could exist between mother and daughter. I thought my duty of a daughter was to make my parents look, and her duty of a mother was to be strict and help me do good in life. I never knew that I could attain this comfortable feeling around her, and feel like she will forgive me and love me no matter what mistakes I do. I felt truly happy. That is until recently I've been telling my parents I want to get a job and move out of the house to study. Every time I would bring the topic up my mom would get the same expression she got back then when I made a mistake, except that she would stay quiet. This feeling I never got before started to grow in me. I felt as if they don't care. My mom has started taking a liking of talking bad things behind people's back. When I go talk to her I usually bring up a topic of someone she had problems with and my mom would get passionate about talking this and that about them. Then later on I would bring the topic of what I want to do in life. When she hears about that all of a sudden she comes up with an excuse to leave or that she's busy. I get so angry but I restrain it. I feel as if she only cares when it comes to talking bad about people, but when it's actual things that are important she can care less. I'm so sick of it. It makes me angry when she talks bad about people, and then she can care less about when I want to talk about my future. When she's not talking about people though she usually talks about all the boys that were after her or how everyone liked her because of how pretty she was. Which I listen to since it's interesting to hear about my mom's past, but then when I bring up something about myself in the past she goes in a jealousy mode where she instantly responds. "That happened to me too, but it was better." I sit there dumbfounded and just listen to what she has to say, and feel as if she can care less about anything I can say about myself or anything good about anyone. I can complement an actress on television, and her instant response is that she's ugly or fat. I just look at her and think what is going on! Is that all she thinks about people. Sometimes I wish I never had to figure this out about my mother. At least when she didn't talk to me I saw her as someone respectable and honorable. Now I see her as any other selfish woman. I don't know what to do. I want to talk to my parents about being more independent and my life goals, but they don't seem to care. The only reason they even talk to me on their own is to tell me to take my medication. They do tell me to leave my room and go outside, but I don't see the point anymore since they don't seem to care and my mom will just talk her daily gossip of my neighbor or family member. It annoys me, and I'm not interested. Gosh at first she wasn't like this, she was different. What is going on? Is it me or is it her? Can everyone tell me their opinion of this. Thank you for reading this long question. Have a great day.
