Writing and depression or anxiety
Writing during depression is good. I think there are two kinds of benefits you can get while writing during hard times.
Trying to write about your current issues will help you to narrow them down. You will feel less drowned into questions if you begin to put them on paper – or any other form, even digital for that matter. Do not try to write a perfect text in one shot.
In that case, what you may write does not have to be perfect. The simple fact of writing, will make you focus on the most important problems first. That is already a great value to be obtained from such a process. Secondary questions will probably come later.
Write something, even if that is a draft first. Maybe you will not even have to edit the text later if you do not plan on publishing it (on a blog) or showing it to anyone.
Doing so will narrow your current issues to the most preoccupying ones and formalize them into sentences that are a little more concrete than just emotions or feeling, making them easier to discuss (with a psychologist a friend or even yourself).
You may have another slightly different approach of writing. Instead of focusing on issues you can write about your expectations, things that you feel are lacking in your life or current situation.
To do so, I would suggest to really let go of any kind of self-censorship, maybe you can even use exaggeration. The idea is to project your expectations. That can be done by thinking that you are writing to someone who is not here to judge you, someone like a perfect confidant, someone who will listen and always say “yes” and support you whatever the situation (be careful, this is not the description of a friend as you may expect from a friend that he/she sometimes slaps you in the face to bring you back to reality).
For example I used the “mail never to be sent” method several times. The name is self-explanatory. Write a mail as if you were about to send if to your “perfect confidant”, but never send it. This point is really important I think: never send it ! You can also do as if you were writing something in your diary to keep it up-to-date.
That piece of text, that part of what you want or what you want to become, should be considered as something belonging to your Secret Garden. There is no obligation to share it with anyone.
However, if you choose to discuss about these projections with someone, you probably can do so, but in any case, do not share the exact content that you wrote ! Indeed the form may be deemed inappropriate or hurtful by your interlocutor (remember that maybe you used exaggeration to write those words). Extract the main ideas and make them the subject of your conversation.
Another essential thing is to write about positive achievements too ! Do not focus on things that go wrong, because you probably also did good things. It is equally important to write about them and discuss them just as you would do with negative things.
Please keep in mind that I only share here my personal experience and my advice. I am not a psychologist. Do not take what I write here for absolute truth. I only hope that sharing these things may help some readers.
