How long have you been in fandom (in general, not specific)? I’ve been in fandoms for going on around 15 years and while I used to write fic and do photo manips and generally was an active part of fandom, these days I find that I don’t have time to do any of that kind of thing and really miss it.
17 years - which, wow, just looking at that number makes me feel so freaking old *laughs* But yeah, I got sucked into the LOTR fandom right after Fellowship came out, and I’ve been in one fandom or another ever since.
And, like you, my interests have ebbed and flowed - there have always been times when I’m more fannishly active and other times when I take a step back and do other things. And that’s fine, and totally normal. Fandom’s not going anywhere, and will welcome you back when open arms whenever you have the time and spoons to engage again at whatever level you find comfortable. <3
