You are not makin a fuss -Im for one is glad you made this important thread to bring up such an important issue. You do deserve help and support - hugs if accepted and please take care of your valuble self.
@Sandstone, I just noticed this thread and have not read the whole thing, so forgive me if I'm redundant of someone else. I just wanted to point out that the way parents react to their kids' problems often depends not only one their education in parenting, but also one of their generation.
I'm older than you, and grew up in a backward town where if kids had problems they were ignored. I was "maladjusted" for several reasons, yet my having problems was not a subject in the family. I was suicidal, but stayed silent, since there was no help. My parents might have tried to help me, but they didn't know how, other than to treat me as "normal" when I obviously was not. The closest thing to a therapist was a preacher offering prayer.
That was post-WWII, when abnormality went unnoticed, unless someone was violently alcoholic or "shell-shocked" from the war. A non-veteran with PTSD was said to have a "nervous breakdown", which was a serious stigma.
I'm not excusing your mother's behavior (or lack of it) but I know that even in my generation, the stigma of being "not normal" could be labelled (heaven forbid) "mental illness"', and could reflect badly on a whole family. Sadly, I think those attitudes still persist in some places.
