These are 2 different subjects. I have noticed, at least for me when I say “I am grateful for having a car, job…” Or whatever that is actually negative emotion because I am acknowledging that 1 some people don’t have those things, or at one time I didn’t have those things. So from now on I am saying I feel good about what I have. I will practice feeling good.
I think you can be grateful and still feel negative emotion towards something. If you just try to feel the positive then that helps a bit.
