FTM and anxiety

He's currently been working night shift (12 hrs) for the past month with a few days off here and there. We hardly get to see each other anymore. I go to work before he gets home, and work while he sleeps. When I get home, we have about an hour together before he leaves for work again. We have just recently relocated to a new state (to me, he is from here). I know no one, and his family is not being supportive of this pregnancy, so I don't even have them. I literally have no one here. So when he is gone, I can't eat, I can't sleep, I have panic attacks if I go more than an hour without hearing from him. I cry all night, on and off, from the time he leaves (5pm) to the moment I get to work (5am). I've lost weight since beginning my pregnancy, and it makes me sad and scared me because I only want what's best for my baby. But I can't bring myself to get out of bed or do anything. I can't hold any food down anymore. I had no morning sickness in the beginning, but now it's an all day thing. I've never been this sad before. I feel like I've always had a form of separation anxiety since I was a baby due to an uncommon upbringing. I used to be independent until I met my SO, but I've always craved being with someone, weather it be a friend or mom or sister. But now that's it's just him & I here, I feel the need to always be around him, or else I go into a huge state of depression. I have started knitting and reading new books and watching new TV series, but I can't focus on those things for too long and than I get sad again and give up. 

I know that I need to talk to my doctor, and I will on Monday. But I am just looking for advice from other mommas who may have ever dealt with something similar. Please, no harsh words. ❤️
