You don’t “have to” do anything…you “get to” do those things. Some people would love to be in your position where you feel like you “have” to do something. Your “curse” might be another person’s blessing.
When you have to go to work to pay the bills…
At least you have a job, which is more than the unemployed can say…
At least you’re able to work…
At least you’re able to provide value and be compensated for it…
At least you have the physical and mental capacity to be able to complete the task in front of you.
At least you can feel like you’ve accomplished something…
It’s ok to not always be happy. But if you’re unhappy for too many days in a row, you need to make an adjustment. Is it your attitude that you need to change or your circumstances? Either might be the correct answer (or both), but instead of just being angry or sad, make a change to feel better. And don’t forget that no matter what you’re going through, other people somewhere have it worse than you.
