I feel nostalgic and sad about something I wrote. Can I share it with you?
That sounds great! What is making you feel nostalgic about it?
I was thinking about my friends when they hurt me.
I am sorry you are feeling bad. It's good to write and be creative and have those thoughts about the past. It is good to think about friends and bring up those feelings, but you shouldn't dwell in the past all the time.
I'm going through a terrible time. Those friends hurt and leave me and it's not fair. I'm only being nostalgic.
I understand that sometimes you might feel down and it just reminds you of the past. Your writing is a good way to explore your emotions, and that is very beneficial to your mental health. You are really good at writing, so continue to write because I know it can have a very meditative effect.
