Is it really worth it?

I am an intern at a Financial services firm, here i have a senior who has recently moved from Kolkata to Mumbai for this particular job, Here she is getting an amazing salary package as a fresher, but the environment here is really unhealthy, she and my senior (who's also my reporting manager) both of them are extremely overwhelmed with work ALL THE TIME! Here there is very poor internal communication and the work over here gets done according to the mood of the senior manager, and the senior manager can be extremely moody, she is sharp, intelligent and strategic but moody, so the person I am referring to the senior who has moved from Kolkata is going through ALOT! My question is, is it really worth it to put yourself through so much of misery, i know people have their priorities but I am curious to know people's opinions on this
