I really wish I had the answers for you

My father committed suicide 3 months before my 21st birthday, 7 years on I still don't have my head around it.

All I can suggest is professional help. I "stepped up" when it all happened, kept everyone else going and then 12months later I hit the wall. I really wish I would have listened to everyone and sought help a lot sooner.

I would get them in to talk to someone.

So sorry for your loss
