Hi and welcome to the forums. This must be a worrying time for you.
No-one on here can or should attempt to diagnose what you have. What we can do is tell you our own experiences and what happened to us.
For me, getting my blood glucose down via a very low carb "keto" lifestyle reduced all my symptoms. Although most went completely, I still have some. I didn't ever have any retinopathy. I allow myself around 20g carb/day. That worked and works for me. Others have found different regimes work better for them.
You don't say what type of diabetes you have - I'm assuming it's Type 2 - or what your last HbA1c level was. If you told us those, it would help people to respond better to you.
Best of luck. This forum is a great source of help and support.
