She has showed some beginning signs of a possible mood disorder, so we've used our experiences to make her feel so not alone and to help her feel like whatever she is feeling is okay and she can always come to us for help.
One time, when my boys were younger, we were having dinner together. My husband, my sons, and myself. I kept tearing up. I apologized and said it was nothing none of them did. My oldest son piped up and said, "sometimes it just happens, right mom? no reason." I was so happy, in a sense, that he understood beyond his age. Then my husband made some light hearted comment about what my son said, and I wanted to kick him hard under the table. You see, this is the son who keeps most things to himself. For him to even open up is an amazing feat.
He is now 17(well, will be in a couple weeks). Over the years from my observations, and even some of his more perceptive teachers, I have noticed he picks up on what others are feeling, even if he doesn't quite understand it. He tends to internalize this. I have tried to help him understand this over the years. He does suffer from depression and tends to think less of himself. I hate this, especially since I've tried hard since the day he was born to make sure he had a sense of worth. And, yes, I do take the blame. I wish he could see what I see. He is an amazingly sensitive man.
What you are doing with your daughter is wonderful. I can tell you my mother had no clue what to do with me and felt she just needed to make me tougher. We didn't talk about any of the trauma that happened. I think she was of the belief that if we didn't talk about it it would make it better. It didn't.
But there is some part of me that just doesn't feel like I deserve to inconvenience her day, week or life just because I'm having a tough time right now
The thing is, though I have had friends who have thought this about "bothering" me, I have wanted them to. It gave me focus outside of myself and it was much needed. Your friend may need this. If she can not help you at this time, I'm sure she will tell you. We all need to feel needed, even in our own chaos.
I hope you reach out.
