So I have major depressive disorder and my treatment has been working really well, I am currently on Wellbutrin.

My problem now is that I am feeling very down, not as bad as before treatment but still very bad. And the reason is most likely because I am currently stuck in a foreign country in South East Asia alone and away from my family. (because of border closures) 

Has anyone been depressed, situationally I guess cince I felt fine before this, while also on treatment? And what can I do to feel better?
