Here is a list of some basic journaling prompts that you can use to begin unfolding any thoughts that get stuck up in that noggin of yours.

Find something to write in.
Pick whichever one jumps out at you and give it a whirl.
Do not censor your writing. Just let it flow out.
Shoot for a time limit and just keep writing until the time is up. 3-5 minutes is a good place to start. Doodle for the rest of the time if you have to :)

Remember that journaling is a tool, one of many that should be in your all natural stress relief toolbox. It's okay if emotions arise during this process, as its just energy that needs to be let out. Often I feel completely relieved and often with more understanding of how to move forward. Journaling is a simple act of self care that can help you to navigate the tricky waters of your mind. Relax and just let it flow.
