I can relate to some extent. I have Asperger's Syndrome which means you ar enot only shy but also uactually unable to interact normally. So it's different from what you have, but I can relate to your childhood experiences. I took was unable to speak a lot of hte time until I was in my early twenties in fact. It was not a language problem, but anxiety. I am sorry your parents called you lazy. Theyd id the same with em, said I was seekign excuses to be different. I hope you can somehow find a therapist who can treat your AvPD. You might also benefit from meds, like an antidepressant, althogh the key is therapy.
