Breakup Advice

So I recently got in a break up. I’m 21 this was my first relationship. We dated for 4 months, but knew each for 2 years. I understand it’s going to be hard and a lot of people say just focus on yourself. My issue is I’ve focused on myself for so long that I’m happy with me, I want someone that I can share my happiness with. I don’t want to go and find a new person right away, but at the same time I don’t want to just go back to how it use to be. So I’m curious on if anyone has any advice at all?
