Hi everyone. I'm really worried about how the last few years will affect my graduate school chances. I'm aiming for an MSc (either taught or research-based) in molecular biology or neuroscience. (My dream program is the Behavioural Science MSc at LSE, that's what I'm aiming for.) To explain my circumstances:

I did really poorly in my first two years of undergrad, at a worldwide top 30 school in Canada. It's a school a little notorious for grade deflation. I studied neuroscience, molecular biology, and English. Most of the bad grades were due to difficulties with undiagnosed autism. Once I received accommodations for taking tests, my grades went up -- I went from a GPA of 1.8 to a cGPA of 3.1 when I graduated in 2020, with a GPA of around 3.6 in my last two years. When I graduated, I was decently set up to do graduate school. I had recent research experience and a few good referees, and I was the Vice-President of my university's student union, which was a nice way to show that I'd handled a big budget, had management experience, etc.

However, when covid hit at my graduation, I didn't know what to do, so I took a year of non-degree courses to try to boost my chances for grad school. This was a mistake, because in 2021, I went through a few difficult situations. I had to move several times due to an unsafe housing situation (I came out as trans, that was partially involved in it), so I've moved house 7 times since 2021. On top of that, around then, I got a really bad case of covid, which turned into long covid, and that wrecked my health for about a year. This resulted in me having to Late Withdraw (LWD, sort of like a DNF -- doesn't affect your GPA but is on your transcript) from one of the non-degree courses I took.

Will this LWD look bad/ruin my chances? It was in a neuroscience course, so it's related to my field, but I didn't have a choice but to LWD from it... I was too sick to complete it, and I was in the middle of moving cities at very short notice. Or are my chances already ruined from the first two years of bad grades? On top of that, I'm really worried that it's too late to contact the referees I previously had, since it's three years out from 2020...

I don't know what chance I even have for a good MSc program. Please help me evaluate my actual chances? Thank you!
