Hello, sorry to hear you are having such a tough time. Getting newly diagnosed is massive for anyone. Keep coming on here to chat and ask questions, we have all been new at some point. Have a browse of some other posts and pick up some tips. I'd recommend getting a copy of this book if you can:
https://www.amazon.co.uk/Type-Diabe...17770520&sr=1-1&refinements=p_27:Ragnar+Hanas as it is fab at learning about the condition and how to deal with it.
Once you have had a few hypos you know you can deal with them ok - it is scary but you can do it. My control has never been perfect, but I manage an HBA1c of 55 (hopefully coming down further) by keeping my levels around 6-8 ish - I'm quite sensitive to insulin so I find if I aim for 4-7 I can end up with a lot of hypos, but this has got better since I got a pump 3 months ago.
What insulins are you on? Being on a modern regime and knowing how to carb count can help you get better control without many hypos.
As for telling people at work, I'm a very private person too, so I made no big announcements when I started my current job. If and when I have a hypo I excuse myself and go drink some pop -no dramas or diva moments. Some people know I have diabetes and some don't, it's not a biggy if I need to explain it but I'd rather not introduce myself to people as a diabetic first and foremost- I'd much rather people got to know me first as a person. One colleague didn't know I had diabetes for 5 years. She described me as "the most unassuming diabetic" she knows! Nobody brings it up ever - because there are just far more interesting things to talk about!
Hope you can get some help soon, make the most of your diabetes clinic team, mine have been fab and they can give you a lot of help, if you work with them.
