is anyone else incapable of basic conversational skills around their crush?

i worry all the time that my crush thinks i'm boring or that i'm distant/indifferent to his presence because i tend to avoid him/not initiate conversation even though i really want to talk to him, but when i do i can barely think about what to say, so i find it really hard to talk to people i'm attracted to because i can't relax. i've tried so hard to just pretend i only like him as a friend to calm my nerves but it's like nothing helps and i'm sabotaging myself
