It was. It was. So again: Kudos to you!
oh my,. that must have been so hard to go through for your family.
:(
How brave and thoughtful of you to consider this! I am the parent of an adult child with bipolar disorder, and I can hardly tell you how grateful I would have been if my son had come to me with a doctor's diagnosis, and how much it would have helped the whole family.
As it is, we learned about it the day he was diagnosed, twelve years ago, after a violent episode, and since then, he has mostly been in denial, refusing treatment. I can't help regretting how much we have all lost as a result.
Go to a doctor and get a diagnosis. Then she can't argue with that and if she does tell her the doctor is a professional in this and she isn't so she has no room to talk.
