Another Bit of Me Not Working...

I had an appointment with my GP this morning. He had contacted me requesting I attend following a recent blood test. In truth it has been a while since I last saw him. He's actually a very good doctor, but I'm acutely aware like many that I don't do everything I should regarding my health and I am often criticised for it.
This morning he told me that my blood test had shown that I have significantly reduced Thyroid function, and that this is probably due to my Diabetes. He asked me if I'd been feeling tired and lacking energy. I replied that I have, I'm tired almost every day and I have nowhere near the energy I once had, even a couple of years ago. He also told me the slowed metabolism will cause weight gain - he only has to look at me to see that is true - and he poked my stomach with a grin.
It has all meant another tablet. This time, it's Levothyroxin and I need to take one daily. This should gradually  return things to their normal level but if not, he told me I would need a course of hormone replacement therapy.
I collected my tablets and I need to see him in a few weeks time after another blood test to see if the tablets have had any effect.
I don't know how I feel at having something else wrong with me. It does explain how I've been feeling most days and how I can easily fall asleep in the afternoon and evening. I'm thankful the tablet is quite tiny as I doubt if there is much room left in my daily tablet dispenser. As it is, I already warrant a NHS carrier bag when I collect my prescription every few weeks.
My GP retires Christmas Eve later this year. I didn't actually think he was that old, but I made a point of looking at him today. He's Chinese and I always think they never really age in the same way we do. He does look young and I would certainly not put him in the 55-60 years bracket. I wish him well and it will be sad to see him go. He's a great GP and he's seen me at my best and at my worst, helping me and convincing me that I had a future after my breakdown.
I've looked up my newly diagnosed condition and it's called Hypothyroidism. If nothing else, I suppose it will be something to talk about at my next Support Group Meeting.
