As someone who used to be kinda similar, it can get kinda addictive! Don’t get too stressed about needing to post or anything, I’d say, but don’t get self conscious either I’d also say. It can be fun to post! And we’ll all be better for it!
I set this up hopefully to try to switch over from Reddit, which I just now logged out of, Bluesky and to a lesser degree Mastodon has effectively replaced Twitter and might do the same for Facebook, and Pixelfed is looking really good so far as an IG replacement.
Welcome to the community, by the way. My name I go by is Leni, though I go by a number of nicknames (more than one actual names in fact due to parentage) and all are okay.
