My boyfriend's friend she has some mental health issues she's bipolar 2 and tends to just lash out or poke fun at people in a sarcastic way. So let's call her E, E messaged my boyfriend and said I was nasty and disgusting as a joke multiple times. It's been over a few weeks since then and I should be over it. I asked my bf why she was calling me nasty and disgusting and he said it's because my trich and me eating my hair and scabs which to her is nasty and disgusting also my hypersexuality , since I sleep around a lot especially when I'm very emotional. I know I shouldn't care what she says. I just wish I can get over it. I've been called worse things for my trich and I have had it for over 12 years. Something as simple as someone (not even to my face) calling me nasty or gross shouldn't get under my skin , but it is. I just need advice to get these negative thoughts out from my head.

Edit: Thanks everyone for the comments , I decided to delete her and leave social media. Today she told my bf after they were smoking at they're sister's house for me not to text her or her sister. But she wanted my boyfriend to tell me instead of her to avoid being mean. So I deleted her and her sister from my contacts. It's making me a bit sad thinking about it because I was super clingy and idolized her obsessing and texting her often ( I might suffer from BPD , I need to get diagnosed but thanks to Covid and losing my job idk when that will be). So that might be the reason why I am not sure , but thanks again for all the nice comments it means a lot. And I'll talk to my boyfriend today about it . Thanks again 💖
