Hi and welcome. There are a few of us on here who were wrongly, me included and your story resonated with me. I was lucky in that I found this forum and while describing my struggles and high blood sugars and weight loss people on here suggested I might have wrong diagnosis and explained things clearly. This gave me the strength to push for help, but it still took 9 months to get diagnosed as type 1 and a trip to A&E.
I would definitely recommend the long and short acting insulins - you will feel much more in control and will learn to fit the diabeted around you, instead of the other way around. Let us know how you get on 🙂
