Is it too late for me? NSFW-ish

I know I'm younger than most people on this subreddit but I can't wrap my head around my life and my sexuality. This is done on mobile so I apologize if there are typos.I'm not sure if my friend likes me, I look up to him and I remember when we were talking when we went to lunch he said "You aren't ugly, you're handsome.". Which clearly made my day but he acts the same now and he's the only one who I've told that I think I'm bisexual. As said, I like him, but is it too late for me? I want to ask him how he feels about me but we're only teenagers and I feel it would be awkward. I don't know.What am I living? Almost everyday I have to watch people around me prancing around happily with their significant other and I'm still sitting here, focusing on my academics but I also have those feelings that I want to have a significant other but I know if I do that I'll slow down on academics. I have those feelings that I want to kiss a guy but never have sex with a guy, only to experiment. I don't want to kiss a girl but I want to have sex with a girl but then those feelings change and then I suddenly have no interest in either gender and I sit there, hopeless.I know I'll get comments saying "Oh you'll get through this" or "You'll find your significant other someday" 'someday' is not today, and I want my academics to stay up and a relationship with someone but i want it now, and then those feelings fade. I don't know what to do. Everyday I cry, and just want someone there to hug but no one's there, so I start drawing as my hobby, and my feelings for the world fade and I'm focused on my art and when I finish, I cry because the feelings come back. I know I can be narcissistic sometimes but I just need someone....
