Is Something Wrong With Me?

My man came home from the army for two weeks for Christmas and he's stayed over at my place for 3 days in a row, and he went back to his place today to stay with his family. That's great, I want him to see his family and I definitely don't want to hog him, he has a huge family and he's been with me for 3 days and we've only spent maybe half of that time going around visiting family. But I miss him so much, I want him with his family but I also want him next to me... He left half an hour ago and I just feel so panicky because I feel like I need him near. I'm scared that he'll get hurt because the highway wasn't plowed and we almost got into at least 5 accidents yesterday and I just worry a lot. Is something wrong with me? can I do something to not feel this way?
