<human>: Can you provide a brief rundown of the text in within 3 sentences?

Backstory : 
My parents had me young. They've both been alcoholics and drug addicts for most of my life. My parents split before I was born. I lived with my mom most of the time, saw my dad for a week maybe twice a year. 

Fast forward to now. I'm an adult (23 y/o) completely self-sufficient. I've never had to ask for money or any sort of help or aide since moving out two and a half years ago. The only help I get from my parents is I'm on my mom's insurance plan. Other than that, I talk to my dad maybe twice a year and my mom maybe once a month. 

I've realized the following : 
- My mom seems to avoid my phone calls. I'll call her house and cell, and text her, but the phone goes unanswered. This wouldn't be a problem if it weren't *every single time I've tried calling*. 

- She obviously favors my brothers. My middle brother is in prison and she makes the 45-minute drive once a week to give him shampoo, but I have to twist her arm to get her to spend time with me on my birthday. 

- I own my own business and have done so successfully, as my sole source of income, for two years. She still asks if my boyfriend, who has a desk job, can get me a "real job". 

- She'll make plans, birthday lunches or the like, and 80% of the time flake out and cancel, with poor excuses. 

- She's never outwardly mean but she makes jokes, comments, remarks that can't be taken as anything but insulting. If I react, she'll tell me to lighten up. 

Despite all this, I still get nervous when I know I'm going to see her, because I want to impress her, to become valid in her eyes somehow.  The more I think about cutting off contact with her, even temporarily, the more I'm convinced this will be a huge weight off my shoulders.
<bot>: My mom is really not a good lady and I've realized her prescience in my life is making it difficult.
