A pivotal point in my life I need answers and opinions.

About me: 49 yrs old, just had cancer removed from my body, travelled the world for 18 yrs as a FOH audio engineer 2 mos. out of each year until 2018, delivered pizzas part time for 18yrs, 2018-2023 unemployed and took care of sickly parents, July 2024 earned CDL, Sept. 2024 hired by a mega and Nov. 2024 resigned from mega, 2025 sales associate in retail, single, no kids, no alimony, beginnings of arthritis. So, after this situation with cancer and hating retail (even though I'm good at it) with knowledge that if I want a future and with upward growth potential I need to do something about it 10 years ago. I have failed.....I was briefly with a mega and went through their extremely brief orientation and OTR time with a trainer pretty much useless. I was set solo and had two reportables in the two weeks before I resigned. The first one I bent a taillight housing on a tanker at a truck stop with the rear driver side of my trailer while pulling forward with the tanker on my left and nobody to be seen for a 100 ft. on my right. I went to some additional training that lasted an hour. Second reportable was at an OC while I was pulling forward between two co-workers and my front blind side trailer corner scuffed (not gouged or dented) the rear driver side corner of a co-workers trailer. No police for both and was trying to avoid backing for both. I was told by my mgr. that I had one strike left so I nipped it in the bud and resigned. I didn't want a firing to be on my employment record even if I never used my CDL again. My mgr. said that I'm welcome to come back ANYTIME whether it's tomorrow or next year. So, 2025 before going into retail I call and was told to call back in 2026 if I have no incidents in my car or any other vehicle. Well, I was about to call when cancer showed up out of nowhere and now that I'm recovering I dread going back to my retail job that I tolerate for low wage, decent benefits and practically no upward mobility. My concerns are about the third strike and what constitutes a reportable as it seems everything is a reportable from blown tires to scuff marks on beat to crap trailers. Other things like too much hard braking that doesn't seem hard, small brief lane departures even due to wind, speed going over 70 for more than 10 secs. going down a hill, 4 wheelers cutting you off sending a signal to HQ for following distance and now the addition of driver facing cameras reporting your hands off the wheel to even touch your GPS or pad etc. etc. etc. It seems everything is a way not only to get you fired but also never hired as a rookie anywhere ever for 7 years at least. Even local small companies that don't use DAC want 1-2 years experience including dumps. I might go through re-training and get fired week 1. I see people at my retail job in their 60's and 70's and think if that is me at those ages then I'm in DEEP financial trouble and my body won't do 8 hours straight of physical work at that age either. What am I looking at here with trucking? Should I live the rest of my life in retail? I would like to have a sit down job 9-5 if I'm not going back to trucking but they all want abilities I don't have like certain computer programs or years of experience. I can't fathom retail being the rest of my life story. I just can't. Please genuine help is appreciated.
