Despite having voluntarily estranged myself from her due to how she treated me, I found an active social media account belonging to my mom, and it's hard not to give into the temptation to take a peek here and there even though there's nothing to be gained from it. It's just a morbid curiosity of sorts, even if she mostly just rants about politics. However, the other day she posted something about my youngest sister having just gotten out of the hospital. For reference, I'm unfortunately largely estranged from my sisters as well, mostly because I couldn't maintain contact with them if I was going to avoid my mom due to them all being much too young to themselves have any independence from her, and I've been told she used that to turn them against me anyway by saying I hated them all and that that's why I left.
Anyway, I unfortunately have my suspicions as to why my youngest sister was in the hospital. A year or two ago she managed to find a way to email me and mentioned struggling a lot with depression (as well as confirming that my mom did convince them I wanted away from them too by opening with knowing that I "don't want to hear from her"), but she never replied to me after I tried to clarify things as well as try to encourage her that things can get better and that I hope her situation improves. Mentioning my sister having just left the hospital is just about the only reference to her that I have seen my mom post, short of a vague request if anyone knew of a good therapist for a young teenager. In comparison, she's posted about taking the oldest sister on a trip overseas (just the two of them, from the looks of it), and threw the middle sister a nice baby shower when she was having a child, now regularly gushing about the baby inbetween political posts.
She then, yesterday, posted some photos of her with the three of them. I didn't notice it right away, but taking a second look (mostly because it's been so long since I've seen any of them that I would never have recognized them as my sisters without the context) I spotted marks all over my youngest sister's arms...
I guess my mom is at least bothering to get her care. Obviously, I wish my sister was doing better to begin with, but when I was struggling with mental health problems myself prior to severing ties with my mom, she was aggressively unhelpful. She brushed off my concerns both leading up to, and during, a mental health crisis. She stood by her then-boyfriend who admitted to having to keep himself from physically assaulting me after I brushed off his completely dismissive and halfhearted attempt at "cheering me up", saying that had he done so I would've deserved it for how I was acting. Decided to try to snap me out of things with ice cream despite me saying that I wasn't hungry, and then chewing me out when I put mine in the freezer instead of eating it because I at least didn't want to waste it if she absolutely insisted on buying it. The morning after all this happened, I overheard her joking with the oldest of my younger sisters about me hurting myself while she thought I was still sleeping, and then while I was on the way to work she soft-evicted me (basically gave me an ultimatum regarding continuing to live there that spat in the face of the established arrangement and made leaving the only choice that made any sense).
She at no point seemed even vaguely concerned about my wellbeing and would continue to be manipulative even after I'd moved out, but before I fully cut ties and also physically moved far away without telling anyone. Frankly, I think that had I done anything drastic, she would've just milked it for sympathy instead of mourning like a normal parent. So, at least my sister isn't going through this. I can't really tell if my mom maybe learned from how she treated me and doesn't want to lose another child, or if my youngest sister is just higher on the totem pole. Mom absolutely plays favorites, and I'm pretty sure the rankings are oldest sister > middle sister > youngest sister > me (her firstborn).
My mom just really sucks as a person.
