I'm a high school junior with ADHD. High school has been really difficult, in ways I can't really describe with words, and I've been pretty happy myself to be able to maintain decent As/Bs throughout. Ever since the middle of soph year, I feel like i've developed depression and anxiety from my family (long story short: parents fight everyday, I get blamed for a lot of things and feel totally useless and helpless) and just in general. I remember it got really bad once and I almost started self-harm (did not in the end, did not have the guts to do it).
My problem is, junior year has been the worst, with school drama, classes, family problems and just everything. My overall grades have dropped and I just feel horrible. My guidance counselor does not know about this or my ADHD and i'm sort of scared to tell her because i don't want to make it look like I'm making an excuse for myself and I'm just trying to gain pity. My junior year grades will definitely reflect badly because they've decreased a lot (from all As and 2 Bs in sophomore year to half and half As and Bs) from my mental health and just dealing with horrible teachers (experienced teachers doing favoritism with students when grading and a teacher who cannot teach the material and just nothing makes sense).
What would be wise decision here, being that I will start applying for college soon?
