Social anxiety has taught me people will reject mean and selfish people. I cannot think about myself all the time, and expect others to like me...have to be more compassionate as everyone has problems in life.Used to think i was the only one with problems, and the world revolved around me.
Taught me i have to be kind and not gossip about others. Help a good person in need without (too many)expectations and he/she becomes a good friend (and nature/god whatever will help me back in unexpected ways).
There is so much to learn...in Buddhism the first noble truth is 'there is suffering in life'. If you don't suffer, you live a lazy life. Am not too sad about having SAD.
It also taught me i have to live in the present moment. Regretting about the past and thinking about the future is not a good way of living.
Long way to go but not complaining right now.
