Granite, I think taking in a scrapbook is an absolutely awesome idea. From what you've written it seems like talking at all in therapy is extremely hard for you, so showing a scrapbook may be a great way to start opening up. Don't pressure yourself to talk about anything difficult - maybe just focus on taling about you are showing her, whether it be photos or the scrapbook or whatever.
Talking will get easier with time. Keep at it.
