Hello, 2 yrs ago sept. I had a double bypass and quit smoking. Since then I have asthma but also I have gained 70 lbs my belly is so big and I'm always tired. Is this because I quit smoking. I have to apply for disability because I can't do my job any longer after 17 yrs I'm not working. Is this depression or something else. I also have a small sore on my arm that doesn't seem like it's healing. Thank you for any information that you can give me
