leaving

Im 17 hi

My boyfriend is leaving for 6 months in a week to go to an art school and im super happy for him dont get me wrong

We've been together for a year now and pretty much live with eachother and theres a lot of doubt settling in me because im scared to lose him and im not sure if i can handle 6 months apart

What should i do? am i pver analysing the most negative outcome?
