How do you feel about me leaving this city that I really hate?
Are you joking? Why do you hate the city?
It's so hard to live in this city and I feel depressed every time I am here.
It's great that you have the strength to leave a place that causes you to feel depressed. It can be difficult to make a big decision like that and you should feel proud.
I'll be moving to another place that I already dislike.
While I don't agree that you should move to a place that you already dislike, you should get out of the city if you hate it there. You shouldn't stay anywhere that makes you feel negative.
