Exercise / Healthy Diet after BC

Thank you! The so called links with obesity that keep getting talked about are realy not helpful to those who have been diagnosed. I was/am obese. Well morbidly obese if I'm honest. But that was the only health issue i had. Cholesterol levels fine. Blood pressure normal. Blood sugar levels normal. So all the speculation about obesity and cancer does my head in at times. Did i cause it. Its my own fault im in this situation. Embarrassed to have to tell anyone that i had breast cancer because i assumed they would just think it was my own fault anyway for allowing myself to get so fat. Then i stop and remember i have 4 relatives with who had this before me. An aunt 2 cousins (mums side of the family) and my sister. Most of whom weren't overweight. What i did have though was an enourmous amount of stress in the years prior to my diagnosis. I dont know if being morbidly obese was the cause of my tnbc at 47. I dont know if the stress was a factor. I have never smoked. Only drink occasionally. Obesity is the only factor on the list that qualifies me other than my family history (brca-) but feeling guilty isnt helpful. I have tried to lead a healthier lifestyle since. In the year after my surgery i lost 25kg. I walked until my joints gave out. Then i swam. I still swim a few days a week and try to eat healthy. Some of the stresses of a few years back are resurfacing and the weight i lost is slowly creeping back on again. I really need to get back on a weight loss track but finding it really difficult.
