I am 22 and am pretty sure that I am in the early stages of Blepharitis. Is this possible, as I know that usually it is uncommon at such a young age.

Blepharitis is not entirely an age-related condition, and it doesn't progress through stages. It can be caused by several different things - some causes are treatable and some can only be controlled. Its possible that you you just have an ordinary infection that has symptoms similar to blepharitis. Its a good idea to visit a doc to find out whats going on.
