I have some growing problems?!

well, im a 14 year old boy from the Philippines. I have this problem since i reached puberty. when i reached thirteen, hair starts to grow in my armpits. i also had pubic hairs already. i started to fell awkward when my hairstyle is not good. i always look in the mirror to look and check my face. BUT, i think im still not a grown up teen. i always want to have a GF, but i don't have one. when i see kids playing, its like i wanted to join them.LOL. when i see people whus age is just 1 year gap with me, i treat them like an OLDER friend. like i call then KUYA which means older friend or older brother in the Philippines. when i saw kids grow, like i saw them from their child hood to their teen age, i would always say " wow, look at them, their big now. not like me. i never grow." and also, when i see kids, like from their childhood to their teen stage, whos voice is now big, i envy them. cuz i think my voice deepen just a little or it didnt. plsss help me.
