DAE get nervous before making large groupchats?

I’m trying to make a group chat for my birthday party and I’m hesitant to create it. I’m just scared no one can come and it’ll be super awkward even though I’m planning it weeks in advance. Also what if people think it’s too soon or I’m trying to overshadow Christmas?

Also in general I don’t like taking initiative like with making big plans and all that. I’m not alone, right?
