Manuscript too long

I am brand new here. I finished my first book, a seven year memior, about a year and a half ago. I have cut over a hundred thousand words (yes 100,000), but I still have a 160,000 word count; I understand that this is about twice as long as a book should be, but after all the cutting I have already done, I am a little uncertain as to what else I can cut; I am destitute, so do not have a penny for an editor, but know that I cannot submit such a ridiculously lengthy manuscript to an agent; any suggestions would be greatle appreciated!

Yes, it covers the seven years I was in an abusive relationship (while also living in Italy, traveling Europe, moving to CT, then CA, and having two children during that time, as well). It begins on the day I met him, and the last page is the day our divorce was final. There is more, but due to the ridiculous length, of course, I am saving that for book two. Thanks for such a quick response!

I will look for that book, and I will skim through my manuscript and see if I am being too showy, too often; thanks!

Thank-you everyone! I will try out the SYW. Although sexual abuse cases exist (Dept of Justice statistics are staggering), unfortunately, not a single book has been written about it; only about physical, emotional or childhood sexual abuse, but not a single one about adult sexual abuse; the entire time I was with him, I searched desperately for a book about it first hand, so that I wouldn't feel so alone. This will be the first one, so others out there won't have to go through it entirely alone, as I did.
My second one will show the last of the abuse by him, and will encompass all the abuse by my second husband (I know, bad habit), and his arrest on Father's Day, 2006, for the gruesome double-homicide of his elderly friends of 25 years. That husband was far more interesting than the first, actually, because he committed every crime you can think of. My second book, needless to say, will also probably end up being far too long, and I will have to figure out how to cut it, too. Thanks again for all your suggestions!

"Since you have done so much travelling, perhaps the words to cut are the descriptions of places upon which your memoir do not actually depend"

Part of the aloneness was due to my isolation on such a small island (northern Sardinia), but aside from that, I will go back and eliminate a lot of the descriptions of my surroundings, which read like a travel log. Thanks!
