I am sorry. Here is what you need to do, if you have not already:
1) Take action. Safe those social media topics and make them available to police. Reason: It will do you good. You may save another child and you will help making society better.
2) Set your sails. Be there for your daughter and your wife. They need you. Give all you can - understand it may not be enough. Reason: It will help you find self worth and at the same time protect you. Coping with regret is much worth that accepting.
3) Allow yourself to grieve.
Your son is not with you anymore, but you have not truely lost your son. PM, if you like to talk.
