Hello..
I have AvPD, was diagnosed in Jan by a psychiatrist. Was previously diagnosed with social anxiety disorder and depression by a different shrink. I had suspected I might have AvPD months before my diagnosis, and when I went to see a GP about it my suspicions were completely dismissed: 'You absolutely don't have a personality disorder'. Doctors in general don't like patients to diagnose themselves (and do their job for them). Because of what I experienced, I would recommend you go and find a GP who specialises/is interested in mental health and maybe even ask for a referral to a psychiatrist. They can assess you, make a diagnosis, prescribe meds if needed and refer you to a therapist. CBT is supposed to be the best form of therapy for AVpD, anxiety etc. I wouldn't recommend psychodynamic therapy, did absolutely nothing for me.
Good luck! Avoidance is the worst and I wouldn't wish it on anyone.
