I need to vent

I'm not good with words and I don't always know what to say. I worry, a lot. Things don't make sense right now and being told the doctors know what they're doing, or they have a plan, or anything along those lines doesn't help. It actually frustrates me more and makes me want to scream, but I can't. Who do I scream and complain to? I know how certain things are suppose to be and when they're not that way, it's hard to understand. Things have been made worse in the past because things were done one way. I don't have a real way to vent without worrying that I will upset someone.
