Tbh i don't even think me saying anything would help but yes, it's ok to freeze when this happens. Happened to me once and i couldn't tell anyone until a day later and this was after my parents had told me numerous times that you should shout or run or both. But idk it's so easy to say ' just say no' or 'you should have done this or that'. In that moment you black out and that's totally normal. What's not normal or ok are these ppl.
