Don't let Type 1 rule your life, you control it! If you don't look after yourself, no one else is going to!
And what if you do give up? Stop blood monitoring, stop injecting and eat what you want. Well, it'll be a slow and agonising way to the hospital...
I may seem harsh, and sound like I have it all sorted. I don't. I have had Type 1 for 13 years now, my HbA1c has never been below 7, is currently 8.3%. My blood glucose is either well over 10, or below 4 - seldom 4-6! But I take the rap for that, kidneys go, ketones set in. But it's up to me to fix it, or live with the consequences. And by the way, I'm a Nutrition graduate, some may say I should know better. We're only human though!
My mum has had Type 1 for 45 years now. She had two children, two marriages, a couple of degrees and is a very successful business woman. She has thee worst blood glucose control and diet I have ever seen! But she doesn't let it dictate her life, then. or now.
Think positive, every day at a time. And don't let highs, or lows prevent you from trying to get it right the next day!
You say you are waiting for an insulin pump, hold in there! My best friend spent her school years in hospital, only when she got her pump did her control improve significantly.
Injections and blood monitoring take seconds to do. And injections shouldn't be so painful. Use new needles not blunt, and try get smaller length needles.
I wish you all the luck! Hopefully chatting to people on this forum, and realising you are not alone might give you some comfort
