Lord, I'm frustrated and moody now... Feeling stress as well... There are so many things to do...

I feel that I'm so tiny and weak... I don't know what I can do. I found that my faith is very very little. I found that I can't really believe in myself. I have worries towards my ability. Am I capable for this? I'm questioning myself... I hate this side of me... Inconfident... Anxious and uncontrolable....
