Goddy :
You are a very good and knowledgable mother. I know this from all your posts.
Your daughter knows that there is something wrong with her "happiness." I just put it that way because I believe that is the way a 15 year old girl wants to think about bipolar disorder. She wants to "feel good". Like she remembers whan she was 11.
Perhaps, you need to take her back to that time. Talk with her how she really felt at that time. Why she felt that way. the key is to "Listen" to how she called "feeling good". Let her do the talking. Let her know you care by only nooding your head. She needs to be incontrol. She wants to let you know that she is willing to help herself.
She is able to handle the computer ? Then the two of you can work together into "google" websites on what causes bipolar disorder. Try to let her find her own answers about "her" disorder. Let her read,out loud to you, what can help her. Stay positive and understanding. But she needs to find some of her own answers
You already have the answers......Let her know that she can find them also.
It's called building on the mother and daughter relationship.... Love
Stabilty will come.....When she has learned.
