Hello Maggie
Please don't apologize for "TMI". This is a safe space, and everything you are sharing is incredibly heavy. It is completely understandable that you are feeling overwhelmed right now; anyone of us would be with everything you have on your plate.
Managing diabetes is hard enough on a good day, but doing it while fighting mental health struggles, painful groin abscesses, and navigating a stressful gynecology referral is an immense burden. Please be gentle with yourself.
Try to take things one small step at a time. Speaking to your Diabetes Nurse about switching the medication, sounds like a good next step.
We are all rooting for you. Please keep posting and letting us know how you are doing, even if it's just to vent. Thinking of you and wishing you all the best.
