I was already on Mastodon by just having a Vivaldi (the chromium browser) account, and it's just lovely I've spent most of the day setting up lemmy, even though I joined feddit.dk 2 years ago, it's only just now I'm taking it seriously.
And, while not related to the fediverse per se, I switched to linux a year ago.
The only service that's hard to drop/switch away from is Youtube imo.

It doesn’t have to be an all or nothing. If you have a decent ad blocker and don’t interact, even if you’re logged in, you’re already out of YouTube. Leave your interactions and uploads to Peertube.

I’ve removed yt from my phone and it was a positive change. I just watch stuff I get like sent or I search for. No more rabbit holes. Also no ads, background playback, playback with the phone locked… the only drawback is that closed captions don’t work full screen.

I’m having more trouble dropping Facebook messenger.

Pretty much everything “real life social” is organized through that. While I haven’t posted anything on Facebook for years, news from my local community, kids after school activities, birthday parties, etc are all organized through that.
