Welcome! I too live in Canada
You will find great support here. This site has helped me A LOT! And I know about eating when you are alone - I am good at that. Just keep thinking - you have lost weight, why put it back on? Try taking the food you dont want to eat out of the house. Cooking a good meal doesnt have to take long

I have frozen chicken breast, fish, seafood, and frozen veggies in my freezer at all times
Good luck!
