Help me

Tati

I’m in a LDR and have been for 4 months. He lives a 12 hour flight away from me and will do for the next two years until he comes back to the UK for uni. I got to see him yesterday for a couple of hours before he flew but now I almost definitely won’t see him until February, which is 6 months away. I have anxiety and he helps calm me down and he promised not to let us break up because of the distance and I don’t want us to break up. I don’t know how I can manage six months without him though. We normally call everyday but we’re both going to be busier these two years with A-Levels and IB so I’m worried we won’t have much time to be able to call each other, especially as I’m doing a lot of extracurricular stuff that will take up a lot of time until December. Does anyone have any tips on how to cope or what to do?
