I suffer from avoidant personality disorder what are the best ways to try on being better socially?

Exposure & practice: Good for you for asking this question! giving in to social avoidance, while it might provide immediate relief, will only perpetuate the problem. Cognitive-behavioral therapy is a good idea for learning to dispute the irrational thoughts about your inadequacy and fears of negative evaluation. A tip is to start where you are now and keep gradually adding more social contact and interactions.
