After a arguement with my mother today over spme trivial matter my sister butted in and suggested strongly i see a therapist. She has been trying to convince me for a while now me and her where sexually abused as a kid however my mother outed her and exposed my sister had been sleeping about and has been sending nudes left and right. She was using the false sexual abuse to hide behind her slut behaviout and in turn caused me great distress. She is a bum who doesn't go uni or work shes 20 turninh 21 this year and relies on our single mother who she gaslights for everything. Im seething right now because i believed her at the start and allowed my self to be emotionally compromisrd i did what she wanted and started to blame my laziness and lack of sucess on her false rape like she wanted to. How does one deal with someone like this whos willing to change reality just to fuck others up and hide her responsibility
