I think some of my problems are the result of being an only child. Because I didn't have any siblings, I didn't really learn how to play with or talk to other children. I remember I tried to make friends in primary school, but I didn't know how to approach kids. They saw how socially awkward I was, so they started bullying me.
I was always shy, I never had self confidence, and I developed social anxiety. I was also really isolated, I think that's the other reason why I didn't learn how to socialize. We never had any guests, we never visited anyone (apart from my grandparents), we only had 2 holidays in 19 years. My parents never allowed me to do sports or any other social activities. I feel like being an only child and being isolated are the main reasons why I am a social failure. I'm 19 years old, but I still don't know how to talk to people.
