URGENT HELP!!?(A levels)

I genuinely, genuinely really, really could use any advice. Please.
If you’ve read all of my posts, you’ll see how comically downhill my education life has gone. Currently, finished first year of my second year 12, with Pyschology, Health and Social and still remaining with Computer Science. I was dealing with a lot of things, some I won’t mention but at this time I was dealing with abuse, thoughts about “going” away, an unfortunate family death, and some other things which hindered some progress for me other than completely being worn out from everything. Sorry to be a bit of a downer, but I do need to add a bit of context. My health and social coursework was finally due in today. I realised I needed some improvements and one of my assignments got corrupted. I explained this to my teacher, and begged her to give me the rest of today to make things right. She refused, took the work that I hadn’t finished and said “it’s not looking good so you may not progress any further.”
Mind you things have been changing for the better, I got a C in both Pysch and Computer Science. However, this is the same teacher that actually took me off Biology and Chemistry funny enough, and refused to allow me to finish my first health and social assignment. (This was in November 2023.)
This teacher has been very unkind to me and actually has really ruined my sixth form experience. Now im going to have wasted two years not even to get anything out of it, as it looks like she’s planning to kick me.
Please help if anyone knows any solutions. Im genuinely stuck here. More stuck than I have ever been.
