Fear?Truth?Secrets?

Have you ever been so confused about something and you don't have the slightest clue on how to figure it out? That it might be easier to just tell someone but you're scared? That maybe they won't accept you, that they'll look at you differently?
I feel like I'm living a lie, that I should tell someone but I don't think I can. How can I when I don't even know for sure. I feel like it's following me around and I'm terrified that someone will find out. It's nothing dangerous, it's not gonna hurt anybody, it's not like I murdered someone or anything like that.
If it doesn't hurt someone, why not share?
That answer is simple, fear of being alone. Fear of losing the few people I care about. But if you keep a secrets and lie and hide things, aren't you already alone? Which is funny because that's exactly what I don't want to be. Sure, I could tell people and the people that really matter will stick around but what about the ones that leave? They then have the knowledge that I don't want anyone to have. Why does everything have to be so complicated or am I making this more complicated than it needs to be?
