Mommies & pregnant mommies... unsure what to do in this unfortunate and very sad situation...?

I am 36 weeks pregnant. My friend is 27-28 ish. We were acquaintances because of work, but when we got pregnant, that brought us a lot closer. We had talked about all the problems etc... we were experiencing. Well at 12 weeks she found out her little girl had Turner's Syndrome and a heart defect. Doctor's kept telling her to abort/terminate because the baby would not survive and every time she want back for an appointment her little one's heartbeat was strong and she was growing. Yesterday I got a text that she went into preterm labor and her daughter ped away! I was shocked. Her little girl had more wrong with her than anticipated, and her little heart was so worn out from being so strong for so long. My heart is broken. They are having a funeral, and I was just curious how to handle it. I want to go, because I loved them both, her and her daughter. It's just that I still have my little girl and I know that will break her heart. Do not get me wrong... I am so happy that my baby is healthy and doing AMAZING, I just do not know how to go about it. I was thinking of just going, because we are still friends and I still should support her, but I am not sure if it would just make it harder on her. What advice do y'all have for me, because I am in total desperation for it???? Also, I know that this might sound crazy but now I am really scared for my baby, I guess. The thought of losing her and just how precious life really is hit me like a ton of bricks yesterday and I cannot help but be just a tad bit more paranoid. I am so grateful she is doing well, but is it normal to have these fears or am I over-reacting? I am just nervous. I am so sad for my friend and would be completely beside myself if I were in her place! I love and am so attached to my daughter right now... I cannot imagine life without her. That's all I can think about. How lucky and blessed I am that she is healthy and that just yesterday I saw and heard her beautiful little heart beating!!! Tell me I am not crazy for being nervous. I am just really emotional right now and have a lot of mixed emotions.I talked to my mom and she said, just be grateful that your baby is healthy which I am and know that my friends little one is with God and all those things that were wrong with her now are perfect in Heaven... I do realize that, too. I am just scared and sad... Advice, words of wisdom, and help as to what I should do, say, or give to my friend to show my condolences are really appreciated!!!! Thank you all so much!!!!!
