That's a really thorough document! I don't know you personally and haven't worked with you, but I'll comment anyway

Your restaurant experiences seem pretty typical for restaurant gigs - fast paced, stressful, lousy supervisors - and short tenures. A lot of it is outside your control - all you can do is choose whether or not you want to be in that kind of environment. You have a knack for figuring out when something isn't a good fit and getting out, which is a skill I wish I had.
You seem to be in a much better place now, determined to leave that career path and move on to something that would be a better fit.
I'd also observe that many of these places, including your current place, have high turnover. It's just more evidence that it's not you, it's them. Building up your confidence will be key.
