New to here so to clarify I don't have any diagnosis and I'm not worried I currently have cancer. My worry is I'm so stressed and sad and lonely I constantly have a tight feeling in my stomach. I've heard it said stress can cause cancer, I'm not saying it's 100%  true, factual or guaranteed just that I'm worried. I'm isolated at home, I'm not excercising enough or eating properly. I know the answer is to do better and I'm trying I'm just so depressed. How likely is a person to develop cancer from being overweight and inactive and always stressed out? If I manage to turn things around is the damage already done? Are there any simple ways to mitigate risk? Are there any signs to look out for? I haven't googled anything because I'm pretty sure I'll just have a panic attack. Maybe it's reassurance I need. Please don't judge me I'm genuinely scared and sad and alone and any kind knowledgeable help is greatfully appreciated.
