Dear Doctor,
Recently, I have begun to have very dramatic mood swings from being very happy to very depressed. I'm a 20 yr old male. I recently started thinking constantly about a repressed memory I have that I was able to forget about and keep out of my mind for the last few years. In reality, i'm not 100% sure this actually happened, and i've always had memory problems, so I am afraid that my mind is like making it up or something. But at the same time, why would I have such feelings of guilt and anxiety if this never happened. Well here goes: I think when i was somewhere between the ages of 8 and 11 that I made out with my sister a few times and possibly engaged in some humping (with underwear on). She is 2 yrs younger than I, we shared a room. I am certain we did not have sex and i didn't coerce her into it or force myself upon her. This is such a weird thing for me to type this, because i cannot be sure it actually happened. (Although i am afraid that is a consequence me repressing this). Recently, it has been eating me up, and I don't know what to do. I have incredible feelings of guilt because i am afraid i have caused her mental anguish or affected her development. Who should i see? Should i talk to her (it has never been mentioned between us). Should i tell her to get help and if so, from what type of doctor/psychologist? What type of doctor/psychologist should i see? I have memories of this thing bothering me throughout my youth and I am afraid that it has been bothering her as well, if not to a greater degree. I don't know what to do and I don't want to mess up my family. I really don't know what to do, but i think i have realized that something needs to be done. If you think someone else can better help me, please provide contact information.
