How can I get better at writing?

I’m miserable! I’ll have to write lots of blogs from now on and my vocabulary, my wordings etc just suck. Is there a quick way to be better at it?

edit: I’ve always been awful at it. I had a passion for it. I remember spending my time writing a “book” on Word Docs (lol) when I was 9 years old! I have so much creativity but I can not put it to words properly. It’s making me very sad.
