Accused of faking disability by a friend despite being diagnosed

I feel gutted that this has happened. To put it mildly, I met this friend online and we hit it off immediately. Me and her would talk often and I genuinely thought she was a sweetheart until I opened my eyes. I do want to say that me and her never met each other in person but we still clicked.

In our conversations, she was aware of my cognitive challenges and would purposefully get mad if I didn’t answer quickly enough. On bad days she would call me insults and berate my self worth. I was always forgiving because I truly valued our friendship. I got diagnosed with autism and adhd not so long ago. She was one of the first people to know about it and her reaction shocked me. She went on a long rant about how she believes I’m lying so she would be more soft on me and later on claims that she has a psychologist friend who says they officially diagnosed me with bipolar disorder? My first reaction was WTF? What psychologist tries to diagnose people online who they never met in person or know anything about? The audacity for this friend to try so hard on discrediting my actual AuDHD diagnosis shocked me. It felt like a slap to the face to the actual real life ones who actually met me in person, knew about my family medical history, had to take multiple tests to get diagnosed, etc. I asked who this supposed online psychologist was but no answer. It was probably all talk and this friend of hers didn’t exist because you can’t really diagnose someone who you don’t know and never met. I later showed her my diagnosis document with my personal information censored and it wasn’t enough for her. She kept demanding I show her the censored parts where my personal information was at. I’m someone who always listens to my gut feelings. Mine was telling me I shouldn’t due to that woman already showing to be aggressive. This led to our friendship breaking apart. Edit: One positive note I want to add is that my family and other friends are supportive of me. I wanted to share my own story because I notice how people with disabilities online get accused of lying about it frequently. My heart goes out to others who been through the same situation as me. Thank you to whoever reads this and have a blessed day.
