Hello,
/u/Phyrrhonix Rather than advice or a personal story, I have a question for you: "What do you want to do?" "What is your personal answer or solution to this problem?"
You went on meds for a reason and you'll get off them when you're ready. The point is that you always have had the agency, you're choosing to take them is just that a choice. Now what choice do you want to make regarding your inability to daydream? It's okay to be lost. The point is that you have the answers within you and all we ever need at most is a supportive environment/people/community that enables and empowers us to make (and discover) the positive choices we have inside.
There's this psychology book I'm still reading through that you might find helpful. I'm familiar with the author's other works and very familiar with the topic so I feel confident recommending it to you. It's called The Child Within by Charles Whitfield

Perhaps doing some "psychological" or "inner child" work might help you unlock your creativity again.
As far as personal stories go, this might sound cheesy to some but I'm only speaking from real-lived experience here. I've found the more I've been able to love myself -- and by love myself I mean develop a physical feeling of love and appreciation and esteem for myself -- the better my life has improved (and with that the ability to write and imagine). I don't mean love as a concept or a definition of love. I mean a physical feeling of admiration and affection floating around in my body. It's taken a lot of work but I believe you and anyone else can achieve it too if it's something you find yourself without in the moment.
Stay strong and keep writing.

This book has been effective for my recovery. It's first edition was written in the 80s:
It's written by a well qualified therapist.
Here's the workbook by the same author:
I would recommend this book on developing self esteem:
This book was more of a "wholesome-kind" of book:
All authors are PhDs in their fields. I've read and applied what's in these books and they've worked. It's a slow and long process. You will have to trust the authors over your gut feelings (which have developed due to habits), which is the hard part.
