Help me save my fiddle leaf fig!!

Hi can you please explain everything to me like I’m 5. We moved this past month and our new place has such better light and Im doing my best to rescue my houseplants. This guy is the most challenging for me. I’ve watched several YouTube videos and what I’ve gathered is I officially have a better light source for it now, I need to be better about watering and take the pot out of the decorative pot when I do water it so I can make sure it drains properly- I was thinking of putting it in my shower whenever I do water it? It’s lost so many leaves on the stem and is drooping so much- do I prune it? How do I prune it? I’m at a loss and need help 🥺🩷 also please don’t judge my monstera it’s been a rough move for these guys
