If you dont have anxiety issues, then half your battle is already won. I Ithink you should go out more with your coworkers, just to practice being socal, if that's what you want.
Try doing some research online about having conversations and just practice & it will become natural. It's just like how we are having this conversation.
You only have 6 posts. So you haven't been too active. You can comment in any thread you are interested in. It's also a way of developing your social skills.
What a Friend we have in Jesus, all our sins and griefs to bear!
What a privilege to carry everything to God in prayer!
O what peace we often forfeit, O what needless pain we bear,
All because we do not carry everything to God in prayer.
-Joseph M. Scriven
