think life’s like that, i have the same problem as u, always worrying until my chinese health physician told me i’m not normal (in a smiling way) because i think more than normal kids these days. but she said all my worrying is feeding on my health and that i should let things go abit. What happens is going to happen, no matter how much u worry. What does not happen is worst as you will not be spending your time enjoying the moments you have but worry half the time!
just let go. i still worry but i worry about things that i have control over and that i can change. take care~
