I think on a daily basis that I only care if I live or not just for my wife's and dog's benefit
What do you mean that you don't care if you live or die?
I feel guilty of not being a good person
Not wanting to live and feeling guilt over not being a good person are strong indications that you might be depressed. Have you tried contacting a mental health professional to talk things through?
Someone told me that stupid and, in no way I've been depressed. I just told you what I think.
Suicidal feelings should not be ignored, if you need help please seek professional services. I can help you find someone if you like that is close to your location.
