My dad was my go-to guy. He died in 1991 in his early 60s from congestive heart failure. He never told anyone he was sick. Complicating things was a severe clinical depression that he was suffering through up until his death. In a small town, there were no specialists to provide the necessary care and he wouldn't seek it out just 40 miles away. I miss him a lot...he would still be my go-to guy today.
