Really Scared And Stressed Out.... Help

so this is going to be a short version of what is happening. I'm new to being an army girlfriend but I wouldn't change it for anything because my boyfriend is the most amazing guy that I know. these past couple of months have been some of the hardest months that I have went through.  I moved to El Paso since he's at Fort Bliss and I'm attending NMSU in Las Cruces which is about an hours drive. I bought a house down in Las Cruces, while I wait for the closing I've been living in El Paso so I can be close to him. He's my everything, when we're together nothing else matters. However,when I first moved down here he checked himself into a behavioral hospitable for some major PTSD and he was having suicidal thoughts. It was an extremely difficult thing to go through. I had no idea that he was going through any of this. He's been out of the hospitable for about 2 months now. These past two months, it seems like at first everything was okay, he was doing better. But latety, especially this week everything seems to be getting worse. For the past two days his chain of command has been trying to get him readmitted but has been unsuccesful because my boyfriend is not having suicidal thoughts anymore. He still is seeing a therapist since he's been out of the hospitable. He goes everyday to therapy and it really does help him. However, yesterday was a horrible day. He went to morning PT and he supposed to come home to change before heading out to therapy. But instead his chain of command took him to the er to have him readmitted. He was there all day. We were texting about what was happening and he kept telling me that he was scared. He's never said anything like that to me before this week even with everything he's going through. It turns out that his chain of command has taken what my boyfriend has said and swtiched it around to making him look like he's crazy. He's been having nightmares about the war so his chain of commaned switched it to being about attacking them instead of being back at war. Finally in the late afternoon he was discharged. The worst part about yesterday it was his birthday. He keeps saying to people it was the worst birthday he's ever had even including while he was depolyed. I know that even though I had nothing to do with what happened it still hurts me to know that I couldn't do anything to cheer him up once he was back home even though I had tried. This whole week I've been so sacred that something really bad was going to happen and there's nothing I can do. Today I couldn't fall back asleep after he left for morning PT because I'm waiting to get that text saying he won't be coming home. I know that I probably sound slefish when other people don't get to see their loved ones for days, weeks, months or even years but I really can't help it. Being in this city without him is hard. I have no one when's gone. I don't have family out here and not to many friends so basically I'm alone which sucks because I don't have anyone to talk to. I can't talk to him because it only upsets him more.
