Can’t handle the loneliness of a LDR? Advice?

My boyfriend and I have been doing long distance for almost 3 years. Out of those 3 years we’ve probably spent a total of 6-7 months together in person. He recently started graduate school and moved across the country for 4 years. I’m in progress of finishing a graduate program but even so I still have 2 years left to finish. An additional 4 years if I decide to pursue another one of my goals. I’m looking at being in a long distance relationship for 5-7 years if I decide to stay with him. However, it’s so hard. It’s taken an emotional toll on me and I’ve been doing a lot to stay busy but at the end of the day I feel tired of being alone. Sometimes I just want to see my boyfriend and spend time with him but that’s not the case. I just want to be loved and be in a relationship where I can actually see the person I’m with. I’m tired of feeling alone and it’s difficult to get the attention I need from my boyfriend. We only talk about once a day which sucks bc communications important for LDRs ;( I love my boyfriend, but I also love myself and I hate being sad and feeling alone all the time.. has anyone been in this situation? What should I do ?
