Our expert says:
Given what you describe I would suggest you contact an organisation called FAMSA.
They are really helpful in dealing with family issues where things have become problematic.
You are very right to be concerned for your sister and she may not be able to fully ask for help herself, but she is a minor and if your mother cannot care for her because of an addiction social services may need to also provide you with assistance. But the first step is for you to consider where to find help for her.
Please visit www.famsa.org and make contact with this service as I think you are right in asking for help at this time, and you also need to care for yourself whilst you are pegnant, and taking on the whole family's stress alone will not be good for you.
