Today I gave a very low pressure presentation in one of my college classes. I didn’t really feel nervous going into it but leading up to the presentation I started to tense up and then started shivering and sweating. My presentation was in an online class so other people probably didn’t notice, but by the end of it, I was shivering almost uncontrollably. My jaw was clenched anytime I wasn’t talking and I felt like I couldn’t get my thoughts under control. Now that it’s over, it’s getting better but I’m still feeling the same thing an hour after I finished. I’ve experienced this for as long as I can remember and it will also happen sometimes when I’m just having a conversation with someone. Does anyone else experience this or know of any ways to help reduce or prevent it from happening?
