Mental health in family

Guys I’m so upset.

I cry nearly every time I see or speak to my dad.

I love him and he has such a good heart but I know he must suffer from some kind of personality disorder.

He believes he is special (can fix all problems), he holds grudges and brings up things I and my mum have said to him from YEARS ago which most people would have moved on from. He won’t ever remember the nice memories he focuses on bad memories and uses them against me.

He will get angry if I try to tell him to move on from it.

It’s like he doesn’t live in the present. He has no friends, he just works 7 days a week. He doesn’t eat properly and just lives off alcohol.

But I don’t think he is an alcoholic. He can go weeks without it. But drinks when he is tired or upset about something.

But on the other hand he can be soooo lovely sometimes and has a good laugh and is so kind.

I find it hard to deal with - I don’t like picking up the phone to him incase he is in one of his moods. 😢

How can I help him without directly telling him I think he has a mental health/ addiction problem??
