I have AVPD, Paranoia, Anxiety, AuDHD, OSDD, and Depression. I get AVPD episodes frequently when I'm menstruating, I get extremely avoidant and will not reply to DM's or interact. And I isolate myself from others, including in real life, and it will be everyone and not just one person.
Please be delicate when I have such episodes, it will determine if I want to stay around you for much longer.
