I am 57, 9 months post surgery, gastric bypass. My emotional reactions are definitely different. I am far quicker to anger, but as someone who previously struggled with depression, I see anger (with cause) as a very positive step. It means I am not internalizing every negative emotion and accepting blame for every little thing that doesn't go as planned. The trick is relearning healthy and appropriate ways to express those emotions. I am happy as hell to work through it instead of holding onto those negative feelings. I started going through menopause about the same time as my surgery, so I really cant know how much is hormonal vs increased confidence and body image.
