I plan on telling her how I feel tomorrow

I’ve had a huge crush on my friend for a while now. Hopefully tomorrow is the day I tell her how I feel. I ran through scenarios through my head, what to do if she says yes, no, maybe, etc. Whatever happens, happens. I’m not sure if I’m ready yet but I’m still going for it, because if she says yes, great, if not, at least I can finally move on and I feel like I can still be friends with her if she says no and I don’t plan on taking it personally.

My biggest worry is that, while I’ve accepted that I’m going to be nervous no matter how confident I present myself, my nerves will get in the way so much that I end up not saying anything. So any chance of a pep talk?
