Is it normal to be concerned that i'm not growing right?

I'm a late bloomer and still growing. Whenever I look at myself in the mirror, I feel that something is wrong with me. For example, I feel that my legs are too long for the rest of my body. I am insecure about this especially when out in public. I feel my head is too small for my body and my arms are too long. Sometimes, I can't stop thinking about it. I often compare myself with other males. That doesn't help of course. I'm to the.point where I almost consider myself a freak. I pray that I will end up normal but it isn't looking good at this point. Is this normal? Any thoughts?

PS: I'm 17 years old male, 5 ft. 7 in. and growing. I used to be extremely small for my age. I lack confidence as you can probobly tell.
