AvPD, despite it's name, is not about avoiding people or avoiding life. It's very insulting to people with personality disorders, which affect every aspect of their lives, for people to self diagnose as avoidant when they are going through a rough patch.

What you're describing is classic depression with self isolation. Again, that is not avoidant personality disorder. I hope you can talk to a therapist who can help you to figure out a plan to go forward in your life. Good luck.
