How best to handle long-distance during quarantine?

I know it’s only a temporary thing, but I’ve only been able to visit my girlfriend once in the last 2 months and it’s just been getting harder to deal with long-distance sometimes. I obviously want to stay together with her because I know we’ll be back together in-person at some point, it’s just difficult. We call daily and that helps but sometimes I feel like the conversation is lacking. Any advice when dealing with these issues would greatly appreciated!
