I knew that this story would most likely have a happy ending considering the title “Deaf Like Me” I made…
Introduction The topic of deaf and hard of hearing young adults in relation to the use of substance abuse (primarily alcoholism) leading to such outcomes such as suicide is not one that is spoken about regularly.
