Not happy

I'm really getting depressed about my current pregnancy. I'm carrying twins on bed rest cause of a thinning cervix. I'm only 21 weeks along and the doctors (being the honest people they are) are telling me I probably won't see 25 weeks. And they're preparing for the worst. It's so bumming because I went into preterm labor 8 months ago at 23 weeks. And my son was a still born. And I could be going through this all over again its heartbreaking. I'm just so over it. Why can't I have a good pregnancy like everyone else!? I'm just bummed out and don't feel like talking to any of my nurses or doctors. They keep sending social workers to my room because they said I'm "emotional less" and "flat". I don't know what they expect outta since I have a possibility of losing my pregnancy and my babies.
