Feeling miserable!

I really just don't know what to do. I am almost 13 weeks along and everything with me is going wonderful! Thankfully. However my best friend, my neighbor who was just a few weeks behind me just had a miscarriage. I feel so terrible for her and she won't hardly talk to me like she used to. I feel like she's upset because she's the one who lost her baby. I don't want to hurt her feelings with all of my progress, but she was always the first person I went to with all my latest news. (After my SO of course) I just feel like I'm hurting her and it's killing me. We sit out and talk everyday and now she doesn't ask me to come out. On top of all of that my belly buddy also recently had a miscarriage. I just feel so bad for these women, I don't understand why they have to go through something so painful. It's killing me.
