Feeling lonely

So my husband just got the news that he will be going to 12 hour shifts starting next week on night shift. He will work every other weekend.. We do absolutely everything together. You don't see us out without one behind the other. With that being said, I'm having a hard time coping with this change. I'm off every weekend, and that's usually when we get "our time" in. Now everything's going to change.. I know I may be being silly, but I don't know what I'm going to do without him.. I really need advice on how to feel better about this
