Does sadness have an end ?

This sadness within me is taking over me and I can't control it anymore. Cried my tears away and the aching pain never leaves . Really need his shoulder to cry on now and I know that will never happen . Really want to hug him and keep him for good but I can't be selfish when he doesn't even want me
Am I worth ? I'm not .
I'm so tired I don't know when can this pain ever be gone . Sick of crying and hurting myself but theres nothing I can ever do . I give up , I want this life to be over so I can be happy once again . I don't want to live in misery and pain anymore, everydays is dreadful as ever and I can't keep this up . I'm reaching my breaking point and I'm snapping any moment.
Jesus , Im sorry I have failed you , I'm tired of being human .
