I understand your frustration and upset
So far, you are doing the best you can with the tools at your disposal, you have phoned 111, and in my opinion can do nothing else apart from keep plugging at it until you see the consultant/speak to your DSN/ get the **** prescription ! No blame for your situation attached to you at all
It may be that you are not insulin resistant, but as
@noblehead and others have said, it's your basal that's playing up, and it won't really resolve until that's sorted out. If it's any reassurance, you are not the only person this has happened to, even when doing fine on a certain insulin for quite a while. The human body is a complicated thing
It will all resolve itself , in the meantime, keep at it. Just think what your levels were at the beginning of this post, and imagine what they would be like if you hadn't put all the hard slog in
