Hello and welcome,
Well you have done well in keeping your levels in a good range for such a long time.
The last few years have been tough on everyone so don't beat yourself up to much. You obviously know what works. My suggestions would be to dramatically reduce the carbs for a while- once your levels improve that may help with the motivation to keep lower carb.
I am another who very rarely eats breakfast- I couldn't find a low carb that I liked and could eat at work so it was just easier not to eat it at all.
Good luck and welcome.
