Yo @sharonleopardi! Good news: there's a Bear-like app called Simplenote that does everything you need. It's kinda like Bear Lite :) I updated the post to mention that as well.
As for where to start... I know that feeling all too well. The best place to start is to just start without needing to figure it out. Usually the simple act of writing will produce results - and then it will just flow into something cohesive. You don't really need to pick a topic. I just start writing about what i happen to find interesting in that moment, and then it evolves into something worth sharing.
There's value in just being interesting and sharing your process ;)
