I Just Don't Know Anymore...

I just don't know what to do. I am not being understood by anyone with anything I say and it is getting worse. Either I am stupid or the world is, but there is a gap between what I say and what others hear. When they say they don't follow me, I try explaining it another way only to be accused of repeating myself. And it is not limited just to verbal communication; my written words are often misunderstood as well. I would continue ranting about it here, but I know it will not be understood so there is little point.
