Trying new tact with my mother to get her to understand me?

[Mrs Flowerpot]

My mother has always opposed anything I do, say etc, It is because I am artistic and creative and she thinks that I "always have to do something different". I think she thinks it is deliberate, but it is actually who I am. I am not that different form most people really, but I have a really wild imagination with lots of ideas. I have channeled this into a creative career. You would have thought she would have understood being a musician and teacher herself, but anyway. So now I have found out why she feels this way (she told my sister) I want to show her that being me is not "bad and difficult" but "good and fun". Many times we have clashed because I have shared things with her and she has either laughed, put down etc. This has upset me and I have withdrawn. Many artists will tell you how sensitive they are and often keep things to themselves. Again she doesn't understand this and thinks I should "tell the world" She gets angry when I keep them to myself - any wonder because I know she will pick to bits anything I come out with. Anyway I have decided to meet her for dinner once or so every week with my partner and talk more about what I am doing - but I would like to monitor what is said. In the past when she has put something down I have often pulled the idea to pieces myself. It makes me unsure of my own plan etc. How would you approach this with her? She is 74 I am 46 and this would be her last chance really to have some kind of understanding of me.
Myth, I see what you mean. It just breaks my heart though and makes me sad. Sometimes it takes all my strength to put up my "barriers" to stop her getting to me when I see her. She loves picking on me in front of others and seeing me squirm. In the past I have become really sick physically and mentally from the stress.
I should have added I still have a successful artistic and profitable career - no problem there.
