Earlier quoted context omitted.
Your logic here amounts to "some people have it bad therefore everyone needs to have it bad". There are many situations where the world would generally be better if a relevant group of people had the option to choose to go elsewhere. When you are part of such a group and don't have that choice it is perfectly reasonable to be frustrated by the state of things.
Frustration is a clue that you need to reframe the problem.
I'm not saying that's necessarily the case here. Just observing that frustration doesn't necessarily imply that you're wrong. Of course the inverse is also true. Being frustrated doesn't mean others are necessarily in the wrong - it might well be your own damn fault.
