After about 3 years of this, in 2019, I was away on a work trip and decided to tag a vacation on at the end. And I just couldn't get out of bed. I couldn't even bring myself to get food sent up to my room. I had already felt pretty suicidal by that point and knew I needed help, so I used work medical to set me up with a therapist.
It's taken way longer than I anticipated, and Covid didn't help, but I'm doing better. I'm far less neurotic, I actually have hobbies, and I've managed to hold down a couple of relationships for the first time in my life. To get to this stage, I needed to seriously take my foot of the pedal: I functionally went down to a part time job (same company, different position) and I had to completely reconfigure my values.
I miss my old self sometimes - the one that would crank all-nighters for work, a job offer or a side-hussle - but I know that old person wasn't going to last very long in the modern world!
