Got diagnosed late last year and still haven't changed anything about my diet or excercise

(Sorry if this post is not allowed I was just hoping to get a little help, and motivation through all this) I just don't know where to start with eating better (should I buy pre-made salads from the store? Start eating more chicken, rice?) . I got to cut out sugar, I know that I have to stop eating processed foods. And take Metaformin (which I haven't been, not good at taking meds on a timely fashion)

I haven't been taking care of myself at all, just in denial. But I'm ready to make a change to control all of this, and feel better. I'll start going to the gym and drink lots more water. ((Btw I got diagnosed type 2, doctors wanted me to lower the sugar mostly))

Thanks for reading. <3 (Also, I live in Canada :) )
