I’m so sorry for the loss of your dad, @ALH, that is devastating. You might want to connect with @Babylee whose dad also died from alcohol related liver and heart disease. They share more in their thread here.
There’s also a recent conversation here which @Ambers started talking about coping with losing a parent as an only child, which you might wish to read.
Our “what does grief feel like?” support page can walk you through what you’re going through right now, and what to expect in the coming weeks and months.
I hope you find the community to be a support to you - you’re not alone.
