Obligate - When you do something just because you feel like you have to

When you do something just because you feel like you have to, even if it’s the worst thing in the world.

I did my math homework because I felt obligated even though I hate math and it’s 3 a. m.

I ate the last slice of pizza even though it was cold and had crusts.

I went to the party because I felt like I had to, even though I didn’t want to.
