Yup. I did it all day and all night because I was so miserable and couldn't do anything else. Nor did I have a desire to do anything because of the super high levels of anxiety, depression, and anhedonia. Probably put 200 hours into it. The anhedonia was 6 weeks, but that showed up about 3 weeks in. The entire thing lasted at a high level for 9 weeks, and then after rapidly improving, still took another 2 months for the anxiety to lighten to the point where it is now.
I don't care if anyone here believes me or not. That's what happened. I wouldn't make this up.
