Your symptoms sound like metformin side effects to me, actually... But that's just a wild guess. Stress can affect the gastro-intestinal tracks too, after all. Are you on met? Also, we can only stab in the dark if you don't measure blood glucose. If you have *symptoms* of being high, you should check and see whether you actually are. Otherwise, there's no way or ruling anything out. Keep in mind that a panic attack can feel a lot like a hyper, and these past months have been stressful for everyone.... Though for some, like you, more than for others. (I am so sorry you've gone through all that!). Stress raises blood sugars, but it doesn't automatically mean insulin. For a "regular" T2, rather than someone trying to carry a child to term, it really is a last resort.
So.. Two questions: Can you check your blood glucose? If you've been on insulin, surely you have a meter about? Check before a meal and 2 hours after, you're aiming for a rise of no more than 2.0 mmol. If you're low on strips, go for dinner, as that's the meal preceding your bad experiences. Second question, what are you eating? High carb, moderate or low carb? A HbA1c of 49 is technically just past prediabetic, and into the diabetic range. You've probably already seen this but still:

Insulin is NOT a foregone conclusion.
Good luck!
