I think about suicide everyday =(?

i cant stop thinking about suicide, i feel so alone and feel like no one will ever understand me or care about me, i was molested as a kid by my stepdad, my family doesnt know, my whole life my mom has put everyone before esp my step dad, and she treats everyone better then me, but i dont understand why, ive always been a good kid and person, never been to jail or did drugs, never, i always show her love, and hug and kiss her everyday and tell her i love her, and NO ONE else in my family does that to her, so i dont understand why she treats everyone better then me, i hardly have any friends, and the ones i do have are fake, everyone i ever met in my life has hurt me, and i been threw alot, i just live in pain everyday, and ive had nonstop health problems for the past 2 years and nothing good ever happens to me, i been waiting and waiting for something good to happen to me for the past 10 years and nothing good has happend, i feel cursed and hurt and lonely and sad all the time my heart hurts all the time and i think about sucide everday i dont kno what to do anymore
