Journaling to stay on track with work and not feeding the bears

Though I am understanding the ins and outs of my work, it's a LOT to keep track of, especially for me. A lot of it may seem common sense to others, but it's a lot of details and noticing surroundings, and in the moment. I think I need to prep myself before visiting each client by journaling out my "common sense" about what I need to focus on and not forget while on the spot with the client. I can do this in the car before going in. At least now I have realized that I can't just go in there and "wing it" like my coworkers do. And I do love journaling - I've got multiple journals going on at once - so just brief notes, maybe to check in on how I"m feeling, but then what I expect/anticipate when going in there - I realize I've been sort of just going in blind, teeth gritted, trying to just get through and get out, but my work has suffered a few times. I'm also realizing that I will stay worked up forever over any mistakes I think I may have made.....it just stays at a high pitch of anxiety. That never goes away. I think I need to just realize that I need to step forward from that - like, yes, acknowledge the cause of the anxiety, but realize I can only engage in any practical solution available, then stop engaging/indulging it - stop feeding the bear that will never go away. Same goes with sadness/discomfort over leaving home to face the day - that feeling will never go away, based on my experience - I am truly a homebody at heart. So I need to just stop feeding that little bear cub, because it doesn't help - eventually feeding these bears, no matter how familiar, causes me to start sabotaging myself and burning out.
