Any Army wives that can give me some advice?

I’m posting anonymously because I know several people who use this app and we haven’t decided to share the news yet.. My husband has decided to enlist in the military and I just want someone to be real with me on what to expect! We have 3 kids so I’ll be taking care of them by myself while working full time. I do have family members who can help and my youngest will start school in August. But I feel like not only is it extremely scary for him to join, it also leaves me without his income. Is military pay enough to cover what we’ll be missing? I’m just freaking out cause I know my whole world is about to flipped upside down. 😔
