I know how hard it is Clinte. I am also 24 years old, and have known I am bi since about 16-17 years old. It was hard, I kept it to myself mostly except for some friends. I didn't tell my mom until she found out from someone else a few years ago, and I still don't know if my dad knows, but I am lucky enough to have a very accepting dad so even if he knows, he doesn't care.
Don't know what to say other than just try to relax and give yourself time to get used to the idea. It gets easier with time.
