This is a hard lesson to learn. If you can learn it then your ahead of the game. I actually think that people who are more sensitive and caring feel more quilt and anxiety than others. People that wear their heart on their sleeve.
Matthew 6:25-34 Do Not Worry~ verse 33-34 But seek first His kingdom and His righteousness and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
