I try to remember the little things I like about going to work. Drinking the good coffee I keep there. Chatting with people in the office. Driving home through the summer weather at the end of the day.
Avoiding the Monday feel is one of the two benefits of a dynamic schedule. The other is running errands, like going to the laundromat or doing grocery shopping, on a weekday.
Last time you asked for help, folks suggested therapy. Have you looked into any of the local free options? My offer of looking for you is still on the table, just let me know what state/province etc!
I think I found the real problem. You won't get strong of you don't lift, you won't get fast if you don't run, and you won't fix your head if you aren't willing to put in effort.
