return to the office

Hello ladies! I’d like to ask some advise/help. As per my work contract I need to go to the office 2 days a week but unfortunately, I have a depression since child birth. My workplace was so kind with me so far and there is an option for requesting a remote contract (so if I would get it, I could always work from home). I really would like to get it as it would take off a huge pressure on my shoulders and I’d like to prepare for the questions (I hope someone who work in HR will also read this post🙏🏻) so if they ask me “Why would you like to get a remote contract instead of prividing fit note in every second months?” then what would be the best answer? (I mean, why am I not happy with providing fit note (this is out current agreement) in every second months?) Thank you so much for any help and advise🩷
