Whatever you were doing it sounds like your boundaries were violated and it went way beyond you in any way inviting what happened to you. You have in some way suffered a loss. For sure a loss of your dignity. Any loss has to be grieved and there are definate stages to grief such as, shock, disbelief, denial, anger, sadness resentment, acceptance, resignation and so forth where all of those things are coming and going in no particular order till eventually the event no longer has a hold on you and you can begin to forget about it without being compromised. Opening up to somebody about all of this stuff is likely to be useful for you. Better out than in!
