I can't help with your depression, other to suggest that you seek help from your doctor, but I can completely empathise with you on the hypos. I've been T1 for 51 years, and start to lose hypo awareness whenever I have too many of them. The last time I had a bad hypo I nearly lost my driving license and was afraid to be home alone. (My husband had to fly to UK for his mother's funeral and we ended up getting our son to stay for a few days while he was gone.)
At that point my team suggested I aim to keep my bgs between 6 and 12 for a while, and that restored my awareness (though it's not as good as it was when I was younger), and I accepted that I wasn't safely going to be able to aim for an hba1c much less than 50. (Not that I've achieved that very often
, but it's nice to have something to aspire to.)
However, technology is a wonderful thing. I now self fund a dexcom, and hypo fear is a thing of the past, as it warns me when my levels go less than 4.4, so I have time to raise them. I don't know what the prescribing rules are where you live, but if you are in a country that hands out cgms to T1s then I'd strongly recommend that you push your team to give you one. (You can pay for a lot of continuous glucose monitoring with the cost of just a couple of emergency hypo hospital admissions.)
But as
@urbanracer said, you should talk to your diabetic team about the hypos and your insulin regime.
Good luck.
