Reddit mentions of Get Well Soon

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
