Hi there, you don’t say how old you are. I am a widow of an alcoholic…so I understand that part very well. If you are younger perhaps tell a Teacher, your Doctor or call Childline …not sure which country you are in? Otherwise tell an Adult that you trust. Don’t cover for them, tell someone what’s really going on.
I don’t think that it’s healthy for you to be living with an addict. On this website look under Help for Families – Finding Support perhaps.
So sorry that you are dealing with this as a younger person as well. It’s a complete nightmare for anyone living with an addict, please reach out and get help. You may be able to get help to get your own council place, to enable you to get away. Good luck.
