Please answer people :/, this is a kinda awkward bit of puberty?

i am 175 cm tall, up to 179 in the morning, which seems ok for a 15 year old guy , but everyone my age is so much bigger, my best friends are all around 6'2 etc and it becomes really embarrassing, also the occasional teasing really doesn't help :( how can i get over my insecurity ? and the teasing ? also is there any probable chance i would reach 6 foot ? although i have hair over my thighs and belly button region, which should be a late stage, i barely have any stubble on my face and wisps on my arms. and my parent's heights if that helps- dad is around 182 cm but mum is around 150cm, and my sitting height is 93 cm ( though not sure how that would help ) anyway please help me people, any comments appreciated
