Were you fingered or groped bc you only made the comment that you were spanked, not only by this male babysitter, but by your parents? You didn't elude that any sexual groping content happened only than what you perceive as sexual. Perhaps you said, but how old were you?
Here is the thing that has been hard for me to realize. I have an adult perspective and a child perspective of the things that happened when I was a kid. I can tell you after several years of therapy that I have a better timeline and framework of what happened now that I have been able to work on some stories. As a for instance, my dad hit my mom and she fell and it somewhat knocked her out. In my child mind, this took 3 days to play out and it felt like hours and hours of this horrific scene. In my adult mind, I realize it was actually about a 5 minute fight resulting in him shoving her and her falling and hitting her head where she likely laid there for a minute or two and got up. When I can look at this through my adult mind, I tend to make it less catastrophic in comparison to when I think of this through my child mind and all I see is my mom laying there unresponsive and it feels like she is dead. Perspective is everything and the only way you can gain that is to get in to therapy and work on it.
I think the reason why you are getting push back about your story is that there are some of us that can see this as a very immature perspective. Be clear!!! I AM NOT CALLING YOU IMMATURE! Your perspective is immature which is not uncommon when traumatic events Andy memories come in to play BUT you aren't doing yourself any favor by allowing that child like perspective to become the pervasive rhetoric in your head. STOP! Get a therapist, get some help sorting it out, work at it bc what you are doing here is nothing short of self destruction. Maybe it was sexual? Maybe this wasn't sexual but you will find something else was. Maybe it has NOTHING to do with being spanked and everything to do with something else. I don't know, but I can tell you that there is more than just being spanked here. Good luck.
