Reddit mentions of Cut

All books listed below(besides the two you listed as read) are linked to their amazon site at the bottom of this post
"It's Kind of a Funny Story" has been my favourite book since it first came out and I'm reading "The Perks of Being a Wallflower" right now. I too am looking for similar books.
I read "Thirteen Reasons Why" a long time ago and thought it was a good book but did not take a liking to it too much.
"Go Ask Alice" and "Jay's Journal" are good reads leaning towards topics of depression.
I started reading "Cut" by Patricia McCormick in a small bookstore but never actually was able to finish it but it caught my attention and I was drawn into the book immediately. After Perks I plan to read it. I haven't been able to read the full length of any of McCormick's books but they all sound intriguing and they are definitely on my list of books to read. I suggest taking a look at her amazon website for her books and what they're about
"Get Well Soon" by Julie Barnes is also on my to-read list.
I think you would like the book "Suicide Notes". I feel like it's one of those hidden-gem books where it is not too well known but is an amazing read. I don't want to give away too much.
So, overall, I recommend checking out:

• Thirteen Reasons Why
  
• Go Ask Alice
  
• Jay's Journal
  
• Cut
  
• Get Well Soon
  
• Suicide Notes

I've already added my two cents into this but I just thought of some books that helped me. Cut and Give a Boy a Gun were books my English teacher made a required reading once things got out of hand.

This ( http://www.amazon.com/gp/aw/d/0545290791) was a good read when I went through that phase. I would recommend it to my adolescent female clients.
