Like what sort of a person gets social anxiety about going to a funeral? How is that my top priority?

I just found out my best friend's parent died and the funeral is tomorrow. I'm gonna go to the before funeral wake thing to bring flowers and give my condolences, I don't plan on staying more than 15 minutes. That's my compromise with the anxiety.

It's awful but I wish I hadn't asked my friend how the parent was doing. She didn't text me with the news (we're close but I'm sure she had other priorities), so if I'd waited another day I would have found out after the funeral. Now I'm an awful person if I don't go and I'm an awful person for wishing I didn't have to. Don't get me wrong I want to support my friend, but I've never been to a funeral by myself before and I feel like I have no idea how to act, what to do. Don't say the wrong thing, don't be awkward, don't make it seem like you feel pity but don't act like you don't care. Jesus.

And on top of this social anxiety freak out my hypochondria is really triggered by this and I worry that seing the body will make it worse. And now I have to sleep while feeling all this anxiety or I won't wake up early enough to get there before the funeral. And again, one of my best friend's just lost a parent and is probably feeling horrible, and here I am making it all about myself.
