help me-.-

so me and my so finally had a weekend off togther in a long time. little that I knew it was going to get ruined. My so just got the call to be at his unit for deployment. I know it's not his fault but I am so angry and upset. this is my first deployment to go through nor do I know how long he's going to be gone. Do you military gf or wives have any advice? Idk I know I'm being selfish idk im just extremely stressed out and worried now and everything. I have no friends around here to talk 2.
