Just broken up

So me and my boyfriend just broke up. But it ended really amicably which I'm pleased about as it could've gone tits up really quickly. It hasn't sunk in just yet but I know it's gonna get a lot harder. Right now I feel quite teary and I wanna cry and I know I'm gonna wanna cry a lot because I already miss him but at the same time it's for the best. Is there any advice you can give me? This was my first relationship I'm 21 we were just in a bad place mentally and needed to sort ourselves out before getting into anything. Any advice would be much appreciated thank you 💛
