Texting anxiety

Does anyone else get text anxiety. Like when one of my sons friends parents texts me I stress super hard at what to say back, I get a rush of panic then I see it’s someone o hardly know and now I have to reply to them. I’m not sure why this happens but it’s so annoying.

For example, my sons friends mom is texting me at the moment asking about a play date for Friday, she sent me a video of a project the kids are working on but I have no idea what to say back. I feel stressed and just can’t bring myself to reply. I never used to have this anxiety, it’s just developed over the past couple years.
