Dumped by Long Distance Girlfriend

It's been about a month since my long distance gf dumped me after only 2 months of being longdistance. She was the one who seemed way more into the idea in the beginning but I think she just wasn't being realistic about how hard it would be. Well there's nothing I can do except continue my life and experience my emotions. Has anyone else gone through smth similar. i miss her so much :(
