For the talking part, I am having the same issues. It's a sign for me that my adrenals are in worse condition, I've had this illness for years, and always when I am at the point of crash and burn, my speech is really bad. Also, have to stay off the phone, talking stresses me out.
I am making small recovery, slowly, and talking is getting better, and can even watch t.v. now, and have been able to turn it up a little more at certain times of the day. Of course this is subject to change because it's very easy to be set back.
You really need to rest and stay away from anything stimulating. Work, phone, t.v. if it stimulates you.
