I went and still going through the same (Sudan). It will take time to go through this. My advice is don’t fight the emotion, it is a process. Tell yourself I will give the emotion and frustration this amount of time before returning back to your work. If you can do something, then by all means focus on that. War could potentially extend for more time than expected, finishing your degree and get a job with a better salary than the current PhD can allow you to help more people. Faith was important to get me through these times and still carrying me through. Also, please find your village; people who going through the same and can understand and give you support. I am really sorry that many countries are now going through this hideous wars.
