Who needs to be able to talk correctly anyway?!

It's currently 9.25pm and I'm in bed writing this post.

The last few days I have noticed my speech has become awful. I am not pronouncing my words correctly, I'm muddling my sentences up or even worse I cannot speak certain words.

It is the most horrible feeling. Not being able to say the word when it's right there in your head and you just can't get it out of your mouth. It's not like you forget what the word was because you're saying it perfectly fine in your mind but you just can't speak the words.
The only way I can explain it is its like being in a nightmare trying to scream for help but no sound comes out (just less terrifying)

I have had my odd days here and now where my speech would play up and I would just laugh it off, but this has been going on for a couple of weeks. It's not an all the time occurrence, sometimes I have no problem; other days I have non stop trouble pronouncing words (like today)

It's so frustrating and embarrassing expecially in front of people that you don't know. 
I have been with my boyfriend 2 years and I would say today was one of my worst dyspraxia days. He tried to correct me and laugh it off with me like normal but this time I couldn't laugh it off and I could feel myself getting emotional and embarrassed.

I have no idea why this has just started up again.  Maybe I'm stressed? Maybe I'm not activating my mind enough? All I know is I can't wait for this to become a "odd day" occurrence again!
