This is my confession.

Throwaway for reasons. This is my confession. My guilt is eating me away and every day I feel the urge to throw up when the memories of my sins come back. I have done horrible things and I cannot forgive myself. I molested my little sister a couple of years ago. I sexually assaulted one of my best friends. I viewed child porn. I've done disgusting things. This is my confession. I cannot forgive myself. Every day I wish to kill myself. I feel sick to my stomach when I think about what I have done. I wish to repent. Can God still forgive me? Every day feels like I am already in purgatory. Please help.
