Thanks for your response, I can only imagine what it feels like to lose your Partner (wife), and have to deal with the emotional impact of your two children. Its what my sister in-law is going through.
I guess from what I have read it is best not to push particular your 15 year old into therapy.
However at that age I feel most children at that age do not have the emotional strength or inner tools to deal with the feelings, and there is a danger in it being turned into a self destructive/medicated behavior as did my brother, when the trauma of our mothers death compounded in him just before his 16th birthday.
Mind you we were around a lot of alcohol influence in the country we grew up in, and the football culture at the time was also geared towards drinking.
Counseling was suggested to us but we were a poor household and we felt like it was going to cost a lot of money, it was not really gently pushed or re-approached with us. I think we also didn't quiet get what it was, and thought whats the point...and didn't really feel like talking to anyone as we didn't know how.
That booklet I mentioned could be a good one to print and just leave with him. It may just prompt him to ask or answer some of the questions by himself, he may also not want to burden you and add weight to your grief.
I guess the impacts of Suicide and the death of a parent at that age is such a personalized situation that there is no one fit all.
What I (or my brother) didn't have was somebody I and my brother felt like I could talk to, or the gentle space then suggestion and nudge towards doing it.
I feel that my nephew has that, at least an adult (Male) that he can talk to, even though he hasn't much there has been the odd txt. Even the txt here and there letting him know I am thinking of him helps I think.
The Alliance of hope (i use the same name) will have some wisdom from people who have been in a similar situation to you and what helped. It is a bit easier and quicker to use in some ways also.
For me (and likely you) even a msg like this helps us feel we can hold each other up in such a daunting time.
And yes if we process and express and transform it we can turn it into a beautiful strength and character that spreads joy and wisdom around us.
