Why don't you join us at the 24 hours club as a starter where we commit not to drink or drug for the next 24 hours? Before you know it, those days do add up and it is a fun way to hold ourselves accountable

Also you mention that your family provides for you and you don't have to do anything. That definitely will contribute to the self centerdness (have you even thought about what your alcoholism is doing to them?)
Anyway, why don't you start volunteering since you don't have to work? That will get you out of yourself and you will meet some good people and break your isolation.
Think about it. It would make you grateful for what you have there are many volunteer opportunities. It's up to you, you can chose sobriety, getting off your behind and facing life or you can keep drowning in your bottle.
Good luck
