Such a terrible tragedy! My heart goes out to his family who must be absolutely devastated. If this was suicide by Timothy, I hope they never blame themselves in any way.
No matter what happened between all of them, if there ever were any disagreements, they are not responsible for any choices or decisions Timothy made.
None of us have the power to cause others to take their own lives.
Conflicts do not cause suicide in mentally healthy people.
From working with the mentally ill for over 15 years, I believe a suicidal person is mentally ill. They are not fully aware of the decisions they are making. They need help and compassion, not judgement.
It appears his family was doing everything they could. They too should receive compassion. Not judgement.
Again, it's a terrible tragedy all around...
