If you could do something over, would you?

That is the question for this post. Would you do something completely over if you had the chance. I know I would. I screwed up the best friendship anyone could ever want by being a very negative person about a happy situation. You wanna know why I did that??? I'm not really sure myself... You see (gonna use fake names here to help make more sense) my friend Nancy and I are really close. We have a friendship that is incredibly hard to find. Once you have a friendship like this you don't want to get rid of it. Ever. You want to keep it for yourself and cheerish every minute of it. That's how much our friendship means to me. I honestly don't know what I would do without her... Saturday she told me some awesome yet not so awesome news... She's going start trying to have a baby. They have 2 kids that aren't even their own but they have full guardianship of them and they are barely scraping by right now. When she told me this news I was completely shocked. Tears started rolling down my eyes because I couldn't believe it. I immediatly jumped on her case telling her that it was wonderful news, but a bad idea because they aren't financially stable as it is. That they should wait. It blew up from there on. She said she thought people would call her stupid for this, but she never thought I would be the one to. I never said she was stupid for it, but the more and more I think about it I see where she's coming from. She wanted my support, the support from her best friend for this and I completely shot it down. But I feel like it is my job as her best friend to tell her as it is. By the end of the conversation she had told me she didn't want to talk to me anymore and to just leave her alone. I haven't heard from her since.
I sent her a text last night, telling her how excited I would be if they were to have a baby. That I will support her through it. But not once within the text did I apologize for what I had told her about being financially stable enough for it. I don't plan on it. I WANT to be wrong about this. I want them to be financially stable enough to do this. I want to see that look in her eyes when she holds that baby for the first time. That joy on her face that I haven't seen in years. I want to be able to hold that beautiful baby myself and tell it just how much I love it and how much love it will always have from so many people. I can't stand the thought of not being there for her through it all.
We've gotten into fights before, but she's never not spoken to me for this long. I miss her. She's the only true friend my age that I have down here. She's the one I go to anytime I'm upset, she doesn't even ask what's wrong sometimes just holds me while I cry and I do the same for her. I'm so scared that I screwed this up. I haven't been able to sleep and I can't rant to anyone abou this because then the rumors will spread or they'll say "she's so stupid for wanting this" I don't want to hear that. I don't want to hear anything from anyone. I just want to let it all out and I can't because she's the only one I talk to about anything really. It sucks. She has so many people in her life that she can talk to. I don't think she realizes just how much our friendship means to me. And I screwed it up. I feel like pardon my language but shit for this. It just sucks. :(
So that night I would do over if I could. I miss her so much. I feel like a piece of me is gone and that sounds so dramatic but it's the truth. I will be supportive of her through this, I will be there every step of the way... if she allows me to.

Sorry this is such a depressing post. I just really needed to write it all out.
