How to find the next career step after 11 years of motherhood.

I am so lost!! I need help to figure out what I want to do next. After art school I became a full time sculpteur for many years, then moved on to being a mountain guide, then studied and got my masters degree in Psychology before finaly working for the movie industry as an assistant director. That was in a past life. For the past 11 years I have been taking care of my two children, who have had health issues, development delays and other problems that have kept me incredibly busy, day and night... But finaly they are both going to school and I want to work again. But I don't know what to do. I feel an artist and am attracted to painting, scupting and furniture design. I feel intellectual and love learning. I feel like a writer and would love to write a novel, write a self-help book, or a script, I love helping people so I feel I could become a life coach. But non of all these ideas seem to hit home. In the past, I have followed each passion and feel very blessed to have experienced success in each one of them but I could never keep it up because I have been such a perfectionnist that I overdid it all and it wasn't sustainable. I have changed, and am still changing, and now I am ready to find what I truly am supposed to do. But I don't know where to start. If you have any advise I am all ears. I really need help. Thank you...
