urgent help needed

wel my engagement isnt officially broken im praying it doesnt break.. my fiance got too angry and told me that i have issues with everything so its over.. we have hardly talked ever since, he told me he needs some time apart from me. i tihnk his ego is too big he needs to realise that sometimes his parents make mistakes too. well my lil sister is engaged and rishtas usually always come for her. i dont want to be the old unmarrried sister. this would just kill me.
how do i be happy? ever since this has happened i have not gotten outta bed. just took sleeping pils and slept now i cant sleep anymore but my head hurts.
