my son used this community, now he’s dead

After my son died a week ago I learned he frequently used this community. My son became 24 years old. He used h periodically. He died of an od. He was a great smart kid with many interests. We are devastated and the grief is total. It is unbearable. We tried in all ways to help him stop using. Now it's to late. I can see several of you have talked to him. He really learned a lot here.
