Help! Should I join?

Razan

Hey, I'm going to be a freshman in college next year, and I've always dreamed of being in the military. I want to work in intelligence, but I have a couple obstacles, which are:

1) My Size - I'm 4'11" and barely itching 100 pounds, so I have concerns over whether I'll be able to pass the Physical Readiness Test, and even if I do, if I'll be taken seriously at all.

2) My Parents - I come from a Muslim background, and they know that I don't want to be a doctor, but I've hid my interest from them in case they reject it completely. Our family is very close, so even though it is my life, family rejection still stings.

Any words of advice helps. :) Thanks.
