Der Patrick66, please do NOT EVER feel "weak and pathetic" for having to deal with a hypo. If you hadn't, AND if someone had found you in time, you COULD have woken up in a hospital bed. (The bad news is, if someone hadn't found you in a state of collapse, you COULD have lapsed into a coma, and POSSIBLY even have died. The good news is, this is a relatively uncommon occurrence, but it COULD have happened ... especially if those around you weren't aware of the dangers or knew how to correctly treat someone in a hypoglycaemic event.)
I am NOT trying to be flippant about what COULD have happened, but I've found myself repeatedly being admitted to hospital for just such a situation.
What I would advise is that you speak with a member of your diabetes support team ... doctor/endocrinologist, diabetes specialist nurse, certified diabetes educator ... and explain to them what you've experienced. It MAY be that a change MIGHT be recommended to the dosage of Metformin that you take, but Metformin by itself doesn't NORMALLY cause hypoglycaemia. It MAY also be that you'll receive dietary advice, explaining the importance of you eating on a more regular basis.
I appreciate that looking after yourself MAY not seem that important to you right now, sir, but doing so over the long-term is incredibly important. IF you can pluck up the courage, I'd advise you to bring up the way you feel with a member of your diabetes support team. It MAY be that they'll refer you for psychological counselling, or refer you back to your GP so that s/he can refer you for psychological counselling. Please do NOT see this as being some sort of failure. It simply means that you need some help/guidance on seeing why you feel the way that you do ... and what to do to 'correct' this.
I wish you well, sir, and truly do hope that you'll speak with someone.
Lots of Love and Light.
Mick
