At job they keep dragging me into public speechs and reunions. I told them I have anxiety but they don't care!

Recently I've been at a party and the speaker called me on stage and told him I didn't want to come but he was "forcing" me in front of everyone, so had to come but was feeling so bad. When someone says "no" this kind of people shouldn't say "ohh come on, come here!" because it's so frustrating.
