I was diagnosed August 2017. I'll be honest the course I went on I found to be useless BUT I've other conditions which weren't taken into account which I found effect blood sugar control so I never went back. The following year I was told I was considered no longer diabetic. In my case I purchased a monitor, everyone told me not to because it wouldn't make a difference but it does, a huge difference. I was able to check my blood sugars when I wanted to and find out ideal ranges at certain times e.g. 90 minutes after a meal or before a meal/bed. I take merformin as well but not a treatment dose.
Things aren't that good anymore. But at the time when I was considered cured I was having more than one seizure a day and it's suspected I was falling into hypoglaecemia - I've a condition whereby I lose consiousness if my blood sugar falls or rapidly increases so I know about that now and keep it higher but more stable.
I found the diet recommendations were horrendously bad for me I collapsed in pharmacy where they took my blood pressure and blood sugars and they were extremely low, when I explained they told me to do the diet gradually - I wasn't going to suddenly die/lose my limbs, I'd had diabetes probably for awhile so I should adjust my eating habits gradually, that really helped me. They were pretty annoyed at what I'd been told and said it happens quite a lot. The course is no longer run here and the only diabetes course that is run is for type one.
There's a lot of prejudice around type 2 and a lot of assumptions by medics as well as general public this is something that you can just control with a bit of effort and not as dangerous. When last in hospital I had a hypo because I was over six hours without food - being "just" type 2 didn't warrant any food, they gave me sugary tea which did nothing and I ended up very unwell.
Every member of my family that's hit mid 40s has diabetes type 2, regardless of size (I'm big because of my disabilties I wasn't before) so when I was told my GP expected me to go into mental health crisis (also have mh problems) but I just said ok so diet or meds. She spent the appointment looking at me like I had two heads, the following appointment she said no one had ever been so calm before - I knew I'd get it so the shock factor just wasn't there for me. She still says that was the calmest she's seen me!
Mental health can be impacted by it as well. I find high and low blood sugars can mimic and even cause panic attacks so bear that in mind as well. For me hypos and hypers are indistinguishable so I carry a monitor to check just in case it's either of those (both can be sorted) or an actual panic attack. I feel no different and have severe PTSD so it's a pain having them triggered by blood sugars.
