Hello.
I just noticed your post this weekend. Unfortunately, but perhaps not surprisingly, this (AvPD) subforum doesn't see a lot of activity. I mostly frequent the related forums for anxiety and depression. But maybe we can generate some traffic here.
I'm in my late 40s as well, and I can really relate to most of what you said. Although until recently, I was able to maintain some hobbies fairly well. Sadly, they were solo activities for the most part.
As for posting, anything you post counts towards the total, regardless of whether it's a reply or not. Other people's replies to you don't count. It's not hard to get to five. Just tell us your favorite ice cream or something.
Sorry, I don't do live chat myself. It makes me anxious.
But there are lots of others. Welcome to PC.
