Welcome to the Forum!
I had to go back and read your other posts to find out what type of diabetes that you have. I went ahead and moved them into this section and created an introduction for you. I hope that you don't mind.
It appears that something they were doing was helping you. Do you know what the difference has been or was, since you were able to participate in the program?
Since you are Type 2 and taking a basal injection of Lantus, it appears that your control is much better. Do you count carbs and bolus for the carbs or have you considered learning to do this? It appears that you are currently using a sliding scale for your insulin dosage (i.e. Humalog: 22 units for breakfast; 23 units for lunch; 25 units for dinner).
Read through the first three threads in the Type 2 Section, when you get a chance, if you have not already done so. These threads will most-likely help you a lot. Self education is one of the keys to successful management of your diabetes, along with a healthy / sensible diet and exercise. Basically, diabetes requires a life-style change for the better. Good luck with your control and management.
