Hello J
I know that this possibility is a terrible blow to you ~ and maybe she will change her mind. It is difficult when you can't see each other. My daughter has a boyfriend, now, and they live a long way apart, but us parents arrange things, so that we can take them to see each other. Is that not a possibility for you two? Couldn't your dads possibly take you somewhere central occasionally?
Now, assuming that she does break up with you, I know that you are feeling terribly down, but just remember that teenage romance often ends after a relatively short time. Some 15-year-olds stay together (the parents of my daughter's boyfriend, for example) so don't give up hope ~ it can happen, but many do not.
It may seem hard to bear now, especially with everything else that you are dealing with, but time heals. When you are just a little older and have more control over your own life, things will get better for you.
By then you may have a better relationship with your girl, because you can see her more often; or you may have found someone new to love.
When you have to deal with something as upsetting as this, it is very important that you tell your counsellor ~ and explain just how important it is to you. You need support through difficult times.
Remember, too, that you have friends on the forum, who are sending their moral support to you.
Try to relax and stay positive.

Good luck
