I'm kind of getting more active now but I had one a month or two back. I was making at least one thread a day and now I can hardly manage one a week so I was blaming it on myself but it's nice to know that other people are going through the same thing
A month or two ago, I was constantly so active on KS and AKP and discord that I couldn't keep up. I ended up focusing on just one (that being discord) and that helped a lot. But it kind of got to the point where I didn't even want to check my notifs on forums. There wasn't a specific reason, I just couldn't bring myself to go on any of the forums for a while. I'm guessing it was because I'd been so active on them, I was going through the 'burnout' stage that you're talking about.
I'm gradually getting more active on KS again now though and making a few more threads. AKP was too toxic but KS is a homely little place for me ^^
