Volunteering work in Kerala.

Hi. I am a 24 year old male who have lived all my life outside Kerala in different states of India, as my dad was in Army. He has retried now and we moving back to Kerala. I wanted to join some volunteering work around Thrissur as to help people of our community and more over make connections and improve my Malayalam skills along with my confidence. I am a extrovert, but coming to Kerala I feel introvert as I am not connected to Kerala and due to language barrier. I do speak malayalam at home but use hindi and English words... Whenever I need to communicate. Even more I guess I am hesitant speaking in Malayalam as I remember my cousins and kids around my home teasing for the weird malayalam I spoke. Would like to know nay community for volunteering or librariers or some other clubs around thrissur.
