I’m scared to go long distance

Well I’m in high school and I knew that if I was going to get in a relationship that it was simply a high school relationship and it would never last or end successfully but this one just happened despite my efforts to not get in a relationship and avoid a future heartbreak. We were friends, then best friends, and now we’re happily dating. It’s my senior year and I don’t want to say goodbye. I know we are going to continue being good friends in college but it gives me so much anxiety knowing that I’m probably going to be the one to cut it off before we leave for college. We are both going to college in state but he’s on one side, while I’m on the other. I truly love this man and i know we are both going to hurt significantly if we break up. Hell, it hurts thinking about it . I know I’m young but I really like this one. I just don’t know if I can go long distance because I’m such an attention whore. It’s not about the sex but just having him there for me is what’s important and I’m just scared in general. I’m not sure if he wants to try long distance but recently we talked about future relationships and I could tell that it broke his heart to think of me dating another guy in college. We’ve sorta accepted the fact that we are going to inevitably breakup but im starting to think that we are still both very attached to each other and that he might want to try long distance. Honestly I just need help on what to do because I just don’t know exactly what to do or how to maintain a potential long distance or just anything in general. He’s also my first love and I know it sounds cliché but im just not sure about anything. Also if you’ve read all of this so far, I applaud/appreciate you. This is quite the paragraph
