This video spoke to me on a very personal level. I too gained a lot of weight during a bad spell, I don't even know my weight, I know it would upset me. I had lost a long-term relationship and my grandmother passed a few years ago within the same month, I turned to a lot of unhealthy things to numb the pain. Food was one of them, I have started walking daily too, YouTube also suggested something called "The Military diet" to me, I haven't started it out of reluctance but I feel that was sent my way for a reason.
Thank you for sharing. <3
