Think about something you're really worried about currently. Get in touch with how the anxiety is affecting you and what the worries are that are spinning through your head. Pick a point down the road when you think this issue will be resolved--maybe a year from now, maybe much longer or shorter. Write a letter to your current self from the perspective of that future self. Share what it's like to have the issue resolved. Tell yourself what you wish you had known earlier. Give yourself advice for getting through this trying time.
