how do you deal with people laughing when you're being serious

I don't know if this can work for you but I continue talking about whatever it is I need to say though there have been a few times when I looked at the person and said "It's obvious I'm taking up your time." then leave.

This is something I always worry about because one of my tics is to laugh and smile. I always have to apologize to who ever is talking to me. I always feel so bad!;

I’ve been there so many times. I just continue until they realise I am serious. It’s infuriating.

Just kidding around here, but you COULD write a little sticky note and stick it to the front of their shirt...something like this:

Some people laugh when they're uncomfortable 🤷🏼‍♀
