Sad and confused and heartbroken

I'm having a rough time right now. I'm missing my boyfriend ALOT. To the point where in zoning out of work and at home. I haven't seen him since April and I don't think I'll be able to see him until the end of year bc of his work schedule. I've been crying all day to the point that I'm second guessing wanting to stay in this LDR. We are almost together for a year now. But not being with him is hurting me. I miss him more and more everyday and knowing his work schedule is up in the air there's no room to plan a visit. I dk what to do. Give up hope, throw the towel in and knowing in my heart he was the one that I was looking for my entire life.
