Let it all out, champ.

I wish I knew how to let my guard down, even if it was just a little. I honestly don't know how to tell my family and friends I care about them or how to just cry in front of others. How do people do it? My whole life I have had to be strong. I have had to hold it together while everyone cries to me. When I am sad, I hardly cry in front of others, I bite my cheeks and hold those tears in for as long as I can. So how do you just let your guard down? Because sometimes I do just want a hug, sometimes I do just want to cry, sometimes I do want to let people know I care about them, I just don't know how? :/
