I am in the process of writing my PhD thesis and it happens to be during the global pandemic crisis. My submission date was supposed to be June 2020 (we are in April 2020), but my supervisor has been kind enough to extend it to September 2020 due to the current circumstances so as to give me more time. However, I feel completely burnout, and I'm scared it will evolve into a depression.
I don't live in the country of my origin, so I am away from my family, support system and anything familiar. I also have a tendency to feel lonely and get stuck inside my head but I went to therapy when I first moved to where I am now and made so much progress. Normally, I have things under control, I go to the gym regularly, and hang out with friends on weekends, play basketball, go on hikes, maintain a relationship with my colleagues at the institute, and volunteer, which all help.
But since we are in quarantine, the isolation and the PhD stress are taking their toll on me, and I feeling super unmotivated, lonely, and defeated. I have extreme self-doubt and pretty much a negative outlook on my personal and professional life. I cry daily and I feel physically exhausted even though I have been getting enough rest and sleep. I try to write, but I can't concentrate. And the more I don't make any progress, the more anxious I become. This is in addition to the feeling of just wanting to be done with this phase and moving forward with other things in life. I feel stuck.
I don't know what to do, and I'm scared it would evolve into depression. What can I do before things spiral out of control?
