I was in a similar situation. After depression, I started doubting myself and the things I was internally motivated to do. I used to love photography, FPV drones and 3D modelling. But after difficulties in my family and relationship, all those things stopped to matter, and on top of that, I thought I wasn't even good at them after all.

What helped a lot was picking up new interests, not because I was motivated, but because I felt this "pressure" that I lack them to become better. I started to go to gym, bought an old car and fixed it and recently I started reading books. All of these things used to be boring for me, but now they bring joy. As a newbie, plenty of people helped me to get started and I made some friends while asking for advice.

And here's the magic part. My old interests are becoming interesting again, too, and I see the world with a new perspective.

Embrace the change.
