I find myself most of the days overthinking, not being able to sleep, suffering from body aches and unable to eat. 

I know for sure that anxiety is part of my life and I have to deal with it (not quite sure if it's depression though). However I would love to have a thought that keeps me going thoughout the day.. 

Most of my days I make the worst scenarios, If feel guilty that I am the worst human on earth and I have no positive thoughts at all..

What's a thought that keeps you going?
What's a thought that keeps you motivated?
What's a thought that saved you from doing the worst to yourself?
