My life seems similar to your friend's life. It's come to a point however, that I worry less.
Things are mundane though, this week, after a week of joining an activity(an online course, which is a breakthrough for me). I do laundry, prep meals, and life seems much of a chore, but the summer is on the horizon, so things seem more bearable than the harsh winter.
I’m isolated, and feel my loneliness. I have a lot of those unfinished projects, and a lot of clutter, but I’m told the clutter is because of anxiety, not a OCD issue.
I've had a lot of help though, and I wonder if that is starting to take hold too. As for my wasteful activities, I've measured them, and slowly reduced the negative stuff.
Worry is part of the panic cycle, and is the thought stream.
The same tactics for breaking that cycle could help, with some tailoring by a professional.
