Breakup help!!!

So my ex and me broke up a couple months ago. We dated for six months. But we are only just now doing the no contact rule.

It’s killing me!! I’m constantly checking his social media and I don’t know what to do about it. I want to move on so badly but I do t know how honestly. I keep wondering if he’s dating again or what he’s doing and it honestly hurts so much. How can I stop myself from constantly checking social media? I have to use my phone to keep in contact with my family so it’s been difficult.
