Hello and welcome,
This is a great place to get information and support. The people here are awesome so it is great that you have found it.
The first piece of advice I would like to give is to get a meter and test regularly. This will give you the Information about what food your body can and cannot tolerate. I like many others have cut carbs significantly. I've gone very low carb others go a bit more moderate. The tests will tell you what you can tolerate.
Read around, ask questions but above all know that there is hope. This does not have to be the progressive illness the medical profession think it is.
Good luck and welcome.
