I have a problem accepting my friend who was raped
I hope you aren't serious! Why wouldn't you accept her anymore?
I do not respect my friend anymore
It is not the fault of your friend that she was raped. You are being selfish and not being understanding of the situation. You need to be there for your friend because if you don't, she will not be available for you in the future.
I can't accept that my friend is a slut.
I'm not sure why you would think that about her. It is not okay to reject someone who needs you. No matter what she does, it is not her fault she got raped and you should be more supportive of that.
