Sounds rough, and hopefully as bad as it gets for you. Would encourage you to not self medicate.
But, perhaps take the opportunity to simplify as a positive. Let's face it - maintaining a fleet of bicycles is real work, especially when there's a big variety of builds/systems. Nothing wrong with trying to make that bulk more manageable to one's personal situation. And when the bikes become a PITA, there are lots of other things to do to help clear the mind. Sometimes when a home improvement/repair project or even a bike build is kicking my tail, I grab my cheap recurve bow, setup a target, and let some arrows fly. Doesn't take a whole lot of my brain power, and all I have to do is focus on that one small section of the target, and release. It helps calm my breathing. No loud noises. Even if it's just for ten or twenty minutes, it helps. Some days I shoot well, and some days I don't. But it never matters. And there are many activities that can provide that.
I wish you well and hope you get a handle on this.
