How do u break a habit?

I don't really want to share what my habit is. It's not smoking or anything like that.
I'm finding it hard to break this habit. Anyone have any tips?
Its affecting me mentally so I really could do with some advice.

Ok I understand it's hard if I don't say what the habit is... I keep looking at social media and the girls who my ex used to like pictures of to check up on them. I've tried blocking them but the urge to look is horrible. It's kind of embarrassing tbh
