Dealing With Deployment

This is the first deployment I have to deal with and I know it won’t be the last....I’m so miserable fiancé and I been together almost 7 years and this is the first time we’ve been apart...I’m sure he needed a break from me lol (I’m such a princess) Any ladies dealing with deployment as well? If so how to you not think about it so much? I’m trying to focus on me losing weight for our wedding but he’s all I think about I just want to get myself together....if anyone has advice please help...Thank you 😊
