triggers😭 tmi warning rape...

When I was a kid I was raped several times by my "step dad" it would happen almost every time he was drunk. I didn't tell till I was a teenager because he was my dad... I knew him since I was 3.. in my mind and eyes he was my dad no matter that his skin tone wasn't the same as mine. I ran away from home because my friend was about to be molested by him and I was protecting her. I got in so much trouble but it was worth it to protect my friend. I finally told when my mom found me and she didn't believe me. To this day I still don't think she believes 100% even though all the court records and police reports have evidence. I was in fact raped. Well tonight I used a shampoo that I didn't realize smelled like the one he used... and now I am sick to my stomach with fear and idk why. I know he is out of prison now so maybe that's adding to it but I'm really not comfortable right now. I don't live near him and neither does my mom but I just feel weird. Help please is this normal?
