Thankful for God' Goodness

I know we can’t avoid sometimes having doubts about our abilities and ourselves, Just like me sometimes I think I’m stupid because I can’t keep up with others, because I’m shy, so I always ask how can I avoid not being shy to socialize more with others? I want to be good at things. But since I always attended our church, I gradually changed from being shy to not. I am thankful to God for changing me into a good example to others.
I am also learning His divine words and I want to know him more.
To anyone like me don’t give up always trust and believe that God is always there for us, to guide us.
