Ok, this is deliberately vague, but if more specifics would help you answer, let me know.
I have a neighbour who I am concerned about. They drink heavily and often spend the evening shouting and screaming. Sometimes they hold animated discussions with themselves. They seem to exist in an alternate version of reality, sometimes. Their daughter seems to try and keep them safe, to the extent they don't really leave the house unsupervised anymore.
This has gone on for years, but seems to come in cycles where they are ok for a while and then very much not ok.
How can I try to obtain some help for them as it seems to be getting worse and the family don't seem to be seeking help themselves.
Alcohol is definitely a factor, but there must be other problems underlying it.
Could I call social services, or is there an organisation more likely to help? I'd rather not leave my name when asking for the help. I am concerned about the person concerned, but also about the impact on the daughter.
