Dear CoffeeGirl,

It sounds like your mother and sister are concerned about you -- even if it does not feel very helpful right now. It is amazing how family members can come up with diagnoses and treatment plans without going to med school.

Is your sister playing the role of the eldest sibling? The one who claims to know what is right for everyone else?

Maybe, don't tell them as much information next time.
My parents don't want to know what is going on with me. Even so, sometimes I tell them just enough information. I might say that I have such and such going on and that I am seeing a doctor who is working on it with me.
One thing about families is that our relationships with family members can evolve over the years -- we can learn to deal with them in a way that is helpful (depends on the family I guess).
I hope that you focus on your self, and mostly ignore their advice (criticism) and suggestions.

M.
