Welcome to the community. There will be lots of links and suggestions forthcoming so stick around.
I’m so sorry about your father. You’re asking for help to quit alcohol.
Yes, it will be best for you and a good way to go through this sad time in your family’s life. Your father will feel grateful that you will not follow in his footsteps/unfortunate circumstances.
Glad you’re looking for help.
Again others will come and post specific links from the site that will be helpful.
Here’s a start.
