scared for school

I'm 5'6 and I'm 13 haven't started my growth spurt yet and I grew 6 inches in a year. I'm nervous no guy will ever love me I'm supposed to be over 6'1 and I'm a little big I'm not fat but bigger than most everyone I know and I'm super nervous about switching schools from private it's a really small school and switching to a big public school I'm meeting all my friends I went to kindergarten With (I went to public until 3rd and 3 different private schools until 8th) I'm finishing 8th in public and I'm super nervous about seeing all the kids I went to school with and I'm scared what they will think now that I'm older
