Not sure if you're still active but I just spoke to my dad on the phone for the first time in a week (parents don't live together) and it was terrible, I had to wait for my breath to catch up with my speaking and in some cases I just kept getting blocked. I do have exams starting tomorrow I think I am anxious/stressed so that could have brought it on. But after reading your post, I want to talk on the phone again and try speaking slowly. The only issue is, I'm not motivated because I know that I have to speak and I have a stutter and I suck at speaking. Like right now, I do but I don't. I'm sure you know what I'm talking about but your post has motivated me somewhat. Thanks for sharing and good luck with all your future endeavours!
