I honestly hate depending on my mother

I feel like i have no type of good relationship with my mom. She always uses her excuse of being a nurse and working 12 hours to not have time for me. I told her that i wanted to lose weight and she asked me why and i told her because i wanted to (im 190). Her response was “maybe you’ll lose weight when school starts or basketball season comes”.. this made me really annoyed and aggravated because its such a stupid ass theory. Im 15 turning 16 in December and im really looking for a job. My dad isn’t in my life so she is “all i have”. I’m tired of doing things on her time and i dont like talking to her about any of my problems because it turns into an argument. Im hoping to move out asap.

She was supposed to be taking me to get my permit today but she says no because of an family issue that wont even take 2 hours to do. Its 11:30am. Does anyone else hate being excited to do something but when its time the plans change? This explains 50% of my life.
