go up to him. greet him like you normally would. and cry. cry until you choke on your own tears. tell him everything. how many therapists youve been to that did nothing for you. how many times youve slid a blade across your wrist. how many times you had stood at the edge, and had gotten so close to jumping. but didnt. all because you would miss him. make him give you sympathy. you want him to show how much he really cares without you telling him to anything. just cry. for him. for yourself.
