Submit an Academic Petition or Appeal

Petition Letter: I am appealing the Faculty??s decision that I request a further extension for an incomplete grade for my course Phil 275.
I noticed that my request may be too late for asking this request since the course is already being counted as a failed one.
I will explain my reasons for this late request and further request about changing F to a further extension for my course Phil 275.
I am currently taking a gap year because of my poor mental condition. I was diagnosed with severe depressive disorder, obsessive-compulsive disorder and severe anxiety disorder. All of these psychological problems prevent me from completing my unfinished work for the course Phil 275. Professor Davies is one of the most respectable teachers I admire, she kindly gives me an extension for completing my work during the summer term. However, since I was unable to complete it. I contacted her in October for further requests, and she kindly approved and told me to request an academic appeal for further extension. But the problem is my psychological condition deteriorated dramatically after October. Because of my severe psychological condition, I experienced several life-and-death situations since I could not control my suicidal impulses.
I returned to China in August and currently still stay in my hometown in China.
My hometown is not a big and prosperous city in southern China and compared to Beijing or Shanghai, there are few psychological services in my hometown. I went to the local hospital in my hometown a few times after I returned home, but because there were so many patients with psychological needs and so few psychotherapy services available, the hospital clinics did not offer psychotherapy services at all. The doctors took the more efficient route of treating patients, that is prescribing medication. And because I terminated my weekly meetings with a counsellor in Canada, I lost the opportunity to talk to a more professional psychologist.
But the problem is I needed to be understood, I wanted to talk to someone, but I couldn't find anyone to talk to, and I cried every day when my psychological situation was out of control. There were sometimes I was extremely self-loathing, I wanted to give up on myself, and I simply lost any motivation to help myself. Not to mention the energy I had to complete my homework, it is barely possible that I can get up to face my daily life. That's why I didn't apply in October after I contacted my professor Davies, I had almost given up on myself in the past period of time. And my fear of not being able to complete the work and my fundamental doubts about myself caused me to delay submitting the request.
The political depression is another issue that affects me a lot since the lockdown and quarantine policy is still very strict in China. I simply cannot understand the policy could be such unreasonable. As a student who studies social sciences, it seems that if I empathize more with reality, the more pain I can feel. I do not have the courage to protest on the street to express the public??s dissatisfaction with the quarantine policy. I do not know how to solve my sense of hopelessness, sometimes I just feel I was abandoned. I was very helpless and did not know who to turn to for help.

The above is a description of my mental situation in the last few months, and my request is to extend my incomplete grade, the reason why I haven't submitted this request earlier is that I want to wait until I can finish my unfinished work. Although I don't know if I can submit this request successfully, I have finished my unfinished work.
So, I am requesting that I can extend my request for an incomplete grade and I hope that I could be granted an extension for this class that I failed. Therefore, I could have the opportunity to change this course's result. I struggled a lot and worked very hard on completing it.
