What has happened when I wrote about myself 6 months out is I really start to feel better about the situation. It's still raw, but having comedic parts or characters help with the healing (and story). There were 2 times that I can think of that really helped me process my loss and get more optimistic about my situation.
After my mom died (I was 16), it was just me and my dad at home (my brothers were off at college)- and although I know I could have processed my own pain a little better, I focused on his because it was easier. I wrote a comedy about widowers. I tired to get in his headspace and it helped me with mine. I guess family trauma is kinda a running theme for me and my work, but so is all the sweetness and comedy that come along with family. You get what you get and you celebrate where you can (and mourn when you have to). I never finished the story (it really wasn't that good), but the writing helped.
The second time was when my first major relationship ended and I wrote a movie that dealt with trying to get over a relationship without filling the void with another relationship (because I hate how some movies end with the main character just finding ANOTHER relationship and BOOM, happy ending). I wanted a story where I was enough. And I made that a comedy too (and let my friends make all the wise cracks about her for me (and WAY more wise cracks against myself too because the truth can be funny)). I give the bright parts their time to shine, and I grieve where I need to (but make sure the characters move forward. And by the end of it, I was much more emotionally whole than when I started.
And if the characters don't press forward (and go to dark places), that can be pretty thrilling to write too (and really pull you out of your own situation and make it more art).
Everyone's process is different. I hope that helps. I also hope you find healing and closure.
