Can't find the words

I can't seem to say anything right these days. What I say has to be just right and exactly what I mean. People get the gist of what you're saying and yet they focus on one detail or word. So I start obsessing and drafting what I want to say in my head 10 times before I say it to make sure I mean it in that way and it will be understood in the way that I meant. Now you see why my mind is jumbled! So I just stopped talking. I give up. Sometimes I do say things incorrectly. I once said "I was so shocked, I almost fell off the floor." My friends laughed. How do you fall off the floor Susan? No idea! haha. I don't think I have a bad sense of humor. But being corrected all the time is just irritating. I feel like I'm back in ESL class with the ugly nun hanging over my head ready to call out every pronoun I used incorrectly. I miss being goofy and messing around. But lately, I just can't relax.
