I used to be a big proponent of "someone else has it worse" logic when something negative happened until I realized that if you operate under the idea you’re not deserving of sympathy because someone else has it worse then only ONE singular person in the world is allowed a break.
Sometimes you should just do things because you can even if they suck, it's not about other people having a less desirable circumstance. It's the fact that you in fact have a circumstance that is modifiable. I think that's why you shouldn't feel bad
