Miss my SO

I never used to be like this, but I think I'm dealing with a bad case of separation anxiety. When my SO went to work or he and I had activities that separated us during the day, it didn't bother me. But now I can't stand it when he or I or both have to go to work. I miss him like crazy and I just can't wait to get home. I've always thought myself pretty confident/indepemdent, but these days I feel a need to always be with my SO. The only things I think have caused my personality switch is I'm 18w pregnant and I've moved to a brand new state. What do you all think? Ideas how I can get control of my separation anxiety?? Thanks ladies.
