Head out of the sand I’m diabetic. I feel so ashamed of myself.

I’m 42 and severely overweight. My dr diagnosed me back in January, (A1C 8.1) and I was to try to control with diet and exercise.

The pandemic threw me off and I guess I just didn’t try very hard. Recent A1C almost identical.

Now I’m starting metformin and have been checking my blood sugar in the mornings.

I just feel like a failure. I should have been able to get healthy. I have all the information - it’s not lack of education. I just can’t seem to make myself exercise and eat better.
Any advice or suggestions?
