Why not say it here

I've known I'm gay since basically freshman year of highschool. Due to my apathetic nature though I found it to bothersome to even worry about dating or anything related to it. Because of this I didn't really think about my orientation until now, the end of my senior year about to graduate. As college comes closer I started to think of making a fresh start by coming out. I want to tell my parents and I'm positive that they'll be cool about it but I still have that irrational fear when I just about set my nerves. I put it off saying I'll wait until the mod shifts closer to the topic such as my dad trading me about getting a girlfriend. I have all these scenarios in my head but I just can't act on them. I know I should do it when I feel ready but I want to tell them. This it's just my rambling to the internet at large, I've read a lot of other posts asking these same lines but it still feels good to have it out there.
