he left me! ☹️

Hi ladies, so today my boyfriend left to boot camp for the marines and this has been so hard for me and it's only day 1. I don't know if any of you on this app has gone through that process but for those that have please give me some advice on how you made it through. Everyone tells me the first week will be very difficult for me just because of the fact that we can't talk as often or until I get used to the fact that he's gone for 3 months. Even though I'm so proud of him and happy , I'm also very sad ! I know I can get through this but I just need some advice. I'll appreciate it very much.
