Hi Ms. Growing Girl.
I know where you are coming from. It is the toughest thing I have ever done to come to grips with this fact.... The organization is not directed by God or his spirit. It is just another man made organization that has done a great job of using the scriptures to their own benefit. There are many reasons I do not believe anymore but the single biggest for me is that Holy Spirit cannot inspire false prophecy.
Its tough to swallow because like you, my whole life I had been confident that I had the truth and everyone else was wrong. Now I have to start over from scratch and sift through my knowledge and feelings to determine what is real or manufactured.
Honestly I am ok with that because now I will make choices and analyze information for myself and come to a personal conclusion that is not influenced by any twisted frame of reference based on my background in the religion or by social pressures from my friends and family in the religion.
Hang in there Sis.
