Sweepy, that's how exposure therapy works and I think you said that's the plan. Is that right? This is something you can do and it will be very hard at first. It will feel devastating at first. At first, you may choke and cry and gasp on the words. Slowly, it'll become possible to say them. I hope you and T have practiced breathing and calming exercises for you to use while doing this.
I stood in front of the mirror and choked it out until I could say the words without choking. When you first start, it'll be all choking and tears and snot as you get it out. Slowly it'll get better.
The words cannot hurt you. They're just words. Words to be said in a safe environment. Just words. It'll be okay.
