Feeling frustrated

my bf is in the army, he still needs 2 years.. this distance is killing me right now.. we usually talk everyday but it's not enough. I try to distract myself but recently I've been feeling very alone. my best friend passed away Dec 26 and I really don't have anyone else. like my chest actually hurts from this sadness.. I know my bf wishes we can be together but he is taking this distance better than me because he has a bunch of friends he's made in the army. so they always go out on their days off and honestly I get jealous seeing his Snapchat stories of him having fun. I realize that's so petty of me so I don't say anything to him.. idk what to do anymore I feel like I'm just stuck in this depressed feeling. I just can't wait until he comes back and we can finally be together..
