Can tell you that you shouldn't feel bad at all because, to begin with, the election of Bolsonaro won't have anything to do with you at least in the middle term. Furthermore, if he plans to promote his platform, he'll need the support of the legislative cameras and the population as a whole, and thus he'll need to deal with the opposition, of which you'll need to cooperate a lot in the years to come.
On top of that, think of why a lot of people decided to elect him, it's not precisely because of his political views, it's because he's the strongest alternative against the laborist parties, most of which are considered corrupt nowadays. You can fully expect people to vote for the PT again for the next term, for example, if Bolsonaro screws up, which is likely, anyway.
At the end of the day, this is just 21st century politics, everything is fine until they start making noticeable changes to your rights.
