I am so sorry that your son passed away. I visit my dad every Saturday and he talks about my brother all the time going over things that he could have done differently. I can see the strain on him and its taking its toll, at least he has me and my sister to offload onto. He was your only son and I cannot imagine how you learn to cope with something so terrible. You ca message me any time to talk about your son if you wish. Sometimes its easier to talk to a stranger than your family.
