I feel I have a type of amnesia. That ,

I'm having terrible hiv and drug resistant Tb phobia , I'm being extremely cautious that I fee what has not happened has happened sometimes, I was waiting near a bus stand and a guy kind of misbehaved until what I remember he did not touch me, but I'm strongly feeling what if he raped me and or abused me and I forgot , there were no ppl in that bus stand , I feel like what has not happened might have happened and I would hav forgotten, there no disease like that as such right , I'm not supposed to do anything, just stop giving importance to such thought right ...I'm feeling like I would have forgotten but something would hav happened for a long time , so that's why I got this thought, it's all in my brain right , I absolutely if I donot remember that means nothing would hav happened it's just me thinking like that ,
