I'm probably overthinking this.
I don't think you're overthinking it at all. Figuring out how much to disclose can be a tough problem. There've been times where I wish I'd reached out to someone sooner and told them more about what was going on so I could get support, and there have been times where I feel like I probably overdisclosed. Around work, mutual friends, etc. I've learned to be more cautious. I've also learned to find those people in my life who I can be completely open with. It can take a long time to get all this dialed in.
