Sexual abuse

Hey guys. I hope your all doing ok and pushing through. I need some advice. Without all the ins and outs of it all, when I was a child I got sexually abused by both my parents. Im 21years old now and only yesterday I confronted my dad about it all because the thoughts have really strengthened since I started to take anti depressants. However he's using the excuse that I'm not thinking straight at the moment. Ive been so scared to confront them for so long because I gathered no one would believe me over them two. Im yet to confront my mum when she gets home but i fear after it all all being out in the open, they will side with each other and play mind games with me and say its all made up. I fear that if they don't admit to it it will drive me insane. Now i know none of you know me personally but i can be 100percent certain it happened, these thoughts have always been around but i feel the meds have brang them to the forefront of my mind. Im praying the guilt will override there pride and the truth will come out but I'm scared they will confide in each other and make sure it never does.
