Firstly, welcome to ReachOut!! Thrilled to have you here 🙂
Secondly, I'm really sorry to hear that the pandemic has been affecting your work and uni schedule. I did my honours year last year during the pandemic, and it was A LOT. I personally find it extremely hard to connect with people online, and studying online can of course be super isolating.
I feel that if you are feeling super overwhelmed it might be helpful to cut down a bit on study, so you can focus and do well on a lesser amount of study? My friend was in a similar situation, working 3 days a week and studying full time, and she found it beneficial to focus on a smaller amount of study while working 3 days (was better for her mental wellbeing). I do get the feeling of guilt and wanting to finish uni ASAP, but I personally feel the benefit of putting self-care first and potentially cutting back if its too much.
You should never feel guilty about taking care of yourself!
Hope this helps (even a little bit)!
