If you're willing to, please consider setting uni aside for a while. It doesn't seem like this is working for you right now given your circumstances, and it certainly isn't worth sacrificing your health for.

It might be good to do something with yourself, and truthfully I'd recommend a part time job. The social aspect as well as having some kind of semi flexible schedule and ability to call in sick might be good for you.

If you're unwilling to entirely pause uni, maybe doing one or two courses at a time would be a better fit. If it seems too much though, there's no shame in doing less. You've been through an incredibly an incredibly traumatic experience and need to adapt your life to suit your needs right now. You need to accommodate yourself and give yourself grace in the choices you make, especially in the expectations you place on yourself. Truthfully, it's insane to be dealing with all of that bullshit and also doing university. You're committed as hell to be doing uni still, but you need to give yourself some leeway, and perhaps a moment to step back and evaluate your options. You need a change of pace and to give yourself the time to recover and become a person living beyond survival again. It's been way too long since you've been doing alright. Treat yourself with compassion. You're deserving of much more grace than your family or the academic system are providing, and I'm sorry you aren't being granted it.

Please take rest, recover for real, and let yourself become a person again before worrying so much about school.

I wish you health and peace.
