I shed a lot of hair too. It freaked me out when I was young but when I realised years later that I was not going bald I stopped freaking out over it. Most of the time my hair is medium length so it's not really because I have long hair, it is thick though so it must be why. They say that when you wake up and you have lost a lot of hair on your pillow while sleeping is when to worry about going bald and this has yet to happen to me (rarely do i find hair on my pillow which is awesome if its really a sign of baldness).
