You're not the only person in the world who has trouble beginning a journal. It may feel strange since you mentioned that you aren't one to write things down, but here are some things that you can get started with.
First, purchase a marble notebook or a nice diary type of book.
Then you can start off by simply writing how you feel in the moment.
Are you content? Happy? Sad? Not in the mood to be around people? You can write about the weather and how it's having an affect on you that morning, afternoon, or evening.
Then you can try to pinpoint why you are feeling those emotions.
For example, just last night I wrote about the accomplishments I made this past week in my journal. Before I realized it, I had listed 9 things. (Did something to help a stranger, treated myself to ice cream, gave myself permission to take a break, traveled upstated to see my best friends, got back into a routine at the gym, etc).
You can create a list of the things you love about yourself.
You can begin to create a list of all the blessings you have in your life.
You can free write (ignore spelling, grammar, etc)about your anxiety and/or depression. Vent about how much you detest it, how you don't want it to stop you from things you enjoy doing, how you basically want to kick the crap out of it.
Later on today I am going to work on personifying my anxiety. I am going to give it a name, write a description of what I think he or she looks like, how I feel about him/her, etc. That way - when/if I begin to have an anxiety or panic attack, I will visualize this "person" and tell him/her to go away. To leave me alone because I'm tried of the same routine. Basically speak to it as if it were someone who irriates me or that I do not like.
I hope these ideas help you a little bit. Let me know if you would like more suggestions
Both of you replyed to the 2 posts I wrote at almost the same time. It's still going to be a challenge for me but now I THINK i have an idea of how to start. I'll give it my best.
