The thing is people are rarely good at handling grief especially when it is out of the norm, e.g., an old parent passing away. If it is something that is more long term, a depression, or similar, something I've noticed is when I've been with a friend through it, they may be thankful but once they come out of it they tend to no longer want to spend that much time with you because you remind them of those times. It may be an acceptable cost to pay but realize that you may help and lose someone. Sometimes, professional help is better.
