My brother is moving away?

He's not really my brother but blood couldn't make us closer. Alots of people post these also about their best friend but I feel this is different. He told me today that his mom will likely take a job offer in Florida. We currently live in pa and were both 17 and dudes haha but this guy has been with me in anything I've done, we walked together all the way to pittsburg which is a good hr away by car! We have done countless things together and this moving situation hasn't yet hit me but I'm truely feeling sadden by the min. Idk this isn't a question but Im glad to share that with ppl
