[ Other - Health ] Open Question : Almost 18, will i grow anymore?

I am almost 18 and am 5'8.5 and only weigh 135. I am small for my age and i dont like it. My younger brother is 5'11 and weighs 170. My older brother is 6'2 and weighs 200. I am extremely small compared to them, however, my mom is only 5'5 and my dad is 5'8. Nobody is adopted either, and even all of my cousins are average height and weight or bigger. A cousin on my dads side is the same age as me but about 5'11 and weighs much more than me. Also, my bones are really thin despite drinking a lot of milk and eating a lot of calories from a healthy diet. Again, ive only had one growth spurt going into 6th grade and then grew slowly up until sophmore year, in which i havent grown more than 1/2 in. I can understand that i may not grow much more in height because of my parents but my bone sturcture is really small as well.
