Vent

I'm an introvert and it's really really hard for me to even interact with people including my own family. We had a family gathering today and when I saw my siblings and parents talking with our cousins and aunts and uncles, I felt really left out because I was just there standing, and when my uncle approached me and asked me how I was doing, I just replied "yeah I'm doing ok" and that was my only interaction with a family member the whole gathering aside from my sister. So I really wanna change and try to improve in socializing please help me.
