I like 1 of my friends.. Idk what 2 do!!

it's been a while since I've came on here, but basically alot of stuff happened in my life all at once, I made up with someone I had drama with, and I started becoming closer with one of their friends. She slept over last night, and I think I immediately fell in love with her. We cuddled alot of the night, kissed a few times. Most of the hang out was just comfortable silence. I've only known her for a few weeks now, but ever since she left this morning, I've been missing her!! It's so weird to me because I've never felt so strongly for someone. Anyway, I don't wanna just suddenly lay my feelings on her considering we only started talking a few weeks ago. I already know I want her to be my GF, but yk.. It's way too early, even for me, who's basically whipped. I was thinking about waiting until November / December to confess but I don't know if its too early or too late, especially because I don't want to miss my chance. Anyway, yeah, this is my post for today, advice VERY welcome!!!
