Another great reason I won't have kids

So my mom and I recently got done texting about how life is over at their house and I'm just angry and confused. My sister and her 3 kids have been living with her and my grandma for a bit after moving out of her husband's place. She has been so goddamn lazy, not helping at all around the house and leaving my mom to take care of and spend time with her kids and my grandma ends up doing their laundry (gross!)

Her excuse? Diagnosed depression and adhd and taking meds that make her sleepy...I understand that because I'm the same with my Paxil, but still. My mom was literally saying this felt like it was killing our family and my sister doesn't seem to care!

She's also very private with her life, which is not necessarily bad, but at least let us know if somethings wrong or if we can help! My grandma is 72 and doing a lot of chores that she really doesn't need to be doing for them. My mom is exhausted too and also works 12 hours.

I remember years ago she used depression for me to watch her kids while I was in college trying to study and pass classes but had screaming children all day and couldn't handle the stress anymore. I refuse to watch her kids for that reason. She definitely doesn't parent well at all and I just feel bad for her kids and the rest of my family...I also wish that she would at least go to therapy or something and try to navigate her issues. As much as I loathe her atm, I am really worried...
