im looking for some advice on how to write an autobio about myself... background alittle bit im going to be writing about growing up in an abusive family and dealing with bipolar and post traumatic stress disorder while ive been an adult and how ive overcome all those obstacles... i just dont know how to write in sentances and where to start chapters and stuff like that.. any help would be nice.. pm me!

I find that deciding on the topics before hand with a rough sentence that covers it I can put things in order

Say you have 5 chapters, think up the titles for each chapter and then write each chapter like a  seperate assiignment.

I would say, check your facts on everything if you intend to get this published.

Just write what went on in your own words rather then worrying about it being fancy.  Just tell your story, write from begining to the end (where you wish it to end).   Rather then worrying about chapters, just write it and then go back through and put them in.

I must say  that based on your description of your autobio, your life sound much like mine (except for the PTSD that is).  You have my sympathies.  Have you read An Unquiet Mind (Kay Redfield Jamieson).  it's an excellent example of an autobio by a a bipolar person.  You might want to read it for inspiration.  It's well written too.
