I do possibly feel similar to you, friend. (If I'm understanding the topic here correctly, heh.) When I reflect on the roleplaying I did in the past, I refer to those memories as my "good old days." Because in those days, I had more energy, more time, more fire in me... After a bunch of stuff happened in real life, the flame of my creative passions kinda died. I also find myself very disconnected with the roleplay community these days because I'm kinda old news and a lot has changed and I'm more socially anxious than I used to was~ Oops.
I can make a few sparks of magic happen now and then, but it's hard! The roleplays I'm writing for currently take so long to make even 1 reply for. But when I do get into those creative modes, I sometimes feel myself accessing those old feelings, too. In rare instances of like "Ah yeah, I remember this feeling, this felt so good back then, feels good now too while it's still here."
