Rather than a destructive escapism, I'd say that it's more of your escapism becoming a bad vice. "Something that you love that makes things worse" is just screaming a bad vice if you ask me. An action always affect something and it's not exactly always in your control. I'd like to think that weighing what is more important to me in every action I take is a good way of doing things. If this certain action I do, which I love, is having a more negative effect more than a positive one, I'd probably stop it. Then again, I can't be completely objective so which I 'value' more would be the one coming out on top.
But in this case it's something that's rather vital. I don't think people can handle great amount of mental stress without taking a break one way or another. And escapism is one common method that's actually quite effective, at least for me. I'd do something to forget things for a while and then tackle the problem later with a refreshed mind. Don't just leave it to solve itself and be on your way since it'll haunt you back regardless. If it can't be solved then at least get some closure or it'll always poke you at the back of your mind.
In the end it all comes down if you're willing to let go of something for the sake of another one. Getting everything you want isn't something that I would call human.
