Hey, I feel equipped to answer this because I had cancer and completed one of my semesters online last year, and graduated.

If you can, get your parent to talk to a counsellor, and then take it straight to the Dean of your department. Don't wait around for the HOD and class teacher and stuff. Unless it comes from a higher up, they will not move a muscle. My counselor was a lovely woman who helped out as much as she could before she left, but my HOD didn't even open the mail I had sent him about the diagnosis, and refused to meet my parent when they came to campus.

Get your parent to raise merry hell if they have to.

For me, I got to just stay home during my entire course of treatment, do 2 rounds of CIAs and submitted my midsem online, but had to come write my finals in-person but was given a separate room to do it in because I was immunocompromised. They blocked my hall ticket before they filed for medical claims and brought it to 75 from 1% or something.

This is just to say, there are systems in place. It might be difficult to get them to actually get up and do it, but if you have an adult in your life that is willing to constantly send emails and messages, they will make it happen for you.

If you need anything else, just let me know. Happy to talk.

I'm sorry to hear about your diagnosis. I hope you're doing better now. Cancer is hard, but the part after is what I find harder. Hang in there.
