Envy: I am so sorry to hear about the hip. Have a weird, but reliable friend whose currently a nurse. Very wise guy whose done it all: aircraft pilot, teacher, army officer, journalist and a few others. If he was your friend, he'd bring over a bottle of jack, get shitfaced, break out a guitar after breaking urban ordinance on backyard fires and sing old songs, then would warn you to steel up: Prospects for broken hips in elderly are not good due to likelihood of post-op infection. I still have your address. But despite my good intention, I can't do booze over international borders, otherwise I'd pass you my reserve twixer, even if it is half-evaporated.
Lyrai: Please excuse me if you've heard this one before, but when I was once thrown into a toxic workplace for too long with no viable alternative for employment. The place was so socially unsatisfying, isolated and broken that it along with my inability at the time to complete education drove me to the point of swimming out to sea to the point of no return one winter's night. Told this one and the details to someone I'm pretty close with, and she told me explicitly that the work situation "is not my fault". Not the situation of how I got there, but the overall toxicity of the environment and that there was nothing I could do, so I should stop worrying excessively.
Lyrai, this situation that you describe with the family, and especially the teacher's situation: None of it is your fault. The toxicity of your Father's mother, or your aunt isn't. The fact that this atrocity happened to your math teacher's friend's daughter is surreal and all the more scary, but it is out of your realm. While I think I still have your address, I can offer you just as meagre offerings as Envy with possible exception of math assistance.
I wish you both all the best. I've too-recently found out how little we are without our bloodlines, for better or worse.
