Lucie welcome to the forum.
This is the right place.Take time get a cuppa and study on here.You will learn a lot from friendly and supportive people who have been through it.We get it
I put my T2 in remission within 6 months and dropped BP and cholesterol and fatty liver etc.It can be done.
I do not wish to lecture but for brevity some bullet points or topics to study here:
Low carb lifestyle ( let’s not use diet).
Get your medical data all of it especially hbA1c
Eat to your meter
Take some exercise even walking
Read up on ‘what have you eaten today’( this lot are inventive ).
It is confusing at first but you have to take control and that requires knowledge and that knowledge is here.
Hope that helps just stick with us and you will be fine.
