Boyfriend on holidays without me

Help! I’m feeling sad, so my boyfriend has gone away for a month on holiday. He planned it just before I met him and we’ve been together for 10 months. This is longest I’lol go without seeing him and I just feel really sad cause I won’t get to talk to him very often due to time zones and both of us being busy. Any tips on this situation and how not to miss him too much? Emotions are the worst lmao
