Bullying

So I got a concussion and kinda lost touch with my friend a year and half ago. About a month ago She sent a rude message on Facebook saying she's blocking me etc. because I'm not a good friend. My boyfriend just sent me screenshots of this message she sent to him where she just called me chicken "poop" and a "witch" (I don't cuss) and said other rude things. I'm debating sending the screenshots to her father and boyfriend. I feel like I should defend myself in some way but she's blocked me so I could go through one of them. I'm also upset that my boyfriend didn't even defend me to her. What should I do?
