So, I started grad school during the Sep 2020 session in lockdown. Within a month or two, I was struggling to reach deadlines for assignments of all the courses. I found the online mode of classes very tedious and just could not perform to my best. The monotonous lifestyle and the pressure of graduate work became too much for me. In the end, I was feeling so demoralized and anxious that basically, I didn't attend the last month of classes. So I got an 'F' in 3 of the 5 courses as I missed the assignments, presentations, exams, etc.
Now I have to face my research advisor about everything that happened. I don't know how to approach him regarding this. I know it reflects poorly on my performance and I feel awful. But I can't change what has happened.
I really do want to turn my situation around and successfully complete my grad school. Please let me know any suggestions for how to proceed.
