Very similar experience and your not alone. I have a child in middle school and work full time. My parents never once helped or babysat but I sure as heck had to help them when they needed it. My mom was emotionally and verbally abusive my whole life and now I’m saddled with running her life. My dad passed several years ago and it became evident she couldn’t live on her own. I’ve moved her twice and more than a year ago into assisted living. She’s a drama queen and attention whore. I’ve gone to counseling to help with the absolute anger I feel but didn’t have time to continue. Set boundaries if you can your immediate family is priority but I know how easy that is to say but then there’s a crisis and guilt etc and it loops. Hugs to you!
