No need to feel guilty
Trying to make the best of a situation in which you are placed (and through no fault of yours!) is honourable and commendable. To do so whilst having compassion on those who are suffering isn’t something about which (in my opinion!) one should feel guilty.
There *is* plenty to feel guilty about (are you helping the poor, the oppressed, the voiceless, etc etc) however, your hardworking and ability to adapt to changing conditions is something that (in my opinion) should be a source of ‘humble pride’.
Well done and good luck to you!
