i know what you are going through. i too have diabetes, high blood pressure,high cholesterol and low testosterone levels. see a doctor about viagra or cialis.
i know it hurts to lose the woman you love. marriage and relationships are never easy. you have to work at them. she was not willing to work through this. it's not easy, but it's time to move on. heal. you will find someone.
i'm not having sex at the moment but i take fish oil, ginsing and have a rx for viagra. your doctor can provide free samples on occasion. sometimes it works and sometimes it doesn't. are you overweight?
i am, but i've lost 30 lbs. and seem to get erections more frequently. i'm trying to lose another 30-50 lbs.
eventually you will find someone who will work with you and accept you for who you are. problems and all.
keep the faith and keep in touch if you need to.
remember - change is good
