Is it okay that I like boys? (I'm a guy) please help?

I'm a boy and I'm 16 years old. I've alwys liked girls and still do but I've realized I also like boys like almost 2 years ago. I'm bi and I've been quite insecure over my uality. Its ben bringin me down and i cry once a day putting myself down about it. Im more ually and emotionally attracted to boys but i do like both but prob boys a bit more. Im just so like lost and confused and a bit miserable. I just drive myself crazy menwhile everyone around me loves me and i have everything but thinking negative about my uality and past bullies put me down and makes me sad. I just really want a boyfriend tofollow my heart and see what its like. Any help or advice on how to be confident an happy an accep myself as I can't change that fact I'm bi? Thanks for any help // advice . (:
