I was wrongly diagnosed with Type 2 - and only found out that I was type 1 when I was in hospital with DKA and the doctor wanted to know why I had not taken my insulin! I was not on it then! So, you are certainly not too old for Type 1.
The seizures that you describe are extreme! Different people react differently to low blood sugar levels. Most feel the effects of blood sugars dropping too low. Others do not feel it but other people notice your loss of concentration, your slurred speech, or in my case talking rubbish and irritability or going pale and beginning to sweat. If you train them well they will be able to tell you to test and deal with it! I find that the times that I do not want to test or eat a snack are the times when I HAVE to, and people have to be quite firm with me!
I have dropped to 1.2 mmols before I know about it, but that is because I have hypo unawareness.
You are unlikely to have a seizure with it. You could set your mobile phone to alarm every so often to remind you to test and learn to listen to what your body is telling you and test in between times if you are feeling unwell!
Continue to wear your skirts if you want to - and make sure you have pretty underwear if that bothers you!
