Long distance relationship!

So I am currently in a long distance relationship, and today marks 2 months away from my SO (2 months probably doesnt sound like a lot but it really is!!!) and we will be together again in 3 months, what can I do to make time go quicker? I am missing him immensly, I have held back the tears for so long and ugh I am just so upset all the time but have to put on a smile !!!
