Memoir or Self Help or Both

Hi lovely writers and artists community.

I'm new to the group but have been reading the useful Q's and A's and submitted a question to an agony aunt and had a hugely helpful reply.

I'm writing my story about adoption from two perspectives touching on a range of emotions from loss to love. I'm not terribly sure if I should just write a memoir and hope people take something away from it or a self help book for people who have experienced a similar journey to me (of which there are many). Or in fact should I not even concern myself with either and just crack on and write? I do actually want my experience to impact others in an inspiring way and those that have read the bits I've written so far have commented that it's tragically beautiful (whatever that means haha) and that it has reduced some to tears! Eeek. Anyhow your comments would be marvellous.

Is it an idea to post a snippet in the shared works area do you think?
