Things I don’t understand about Blogging

TLDR: Blogging isn’t as easy as I thought.

I have my current website through GoDaddy but now I’m trying to figure how to mush the two together. I just purchased something on Godaddy that I thought would do that but it doesn’t work. Meanwhile I’m still trying to understand how to use WordPress and when they finally do merge which website builder am I using? Just the WordPress I would hope so I could cancel the other. If I move everything over to WordPress will I lose my work email now? How do I keep that open? I guess I have to move everything over to Godaddy then? But then do I have to pay extra on WordPress too? Who knew it would be this complicated?
