My main character has a 1st person POV. I'm having trouble conveying emotional dysregulation, unresolved anger and random mood swings within the narrative. Emotions can be quite difficult to get down onto paper anyway but in a character that also has difficulty in reading emotions in other people is even harder for me. It's not good writing to say "Now I was angry... Then I was bawling my eyes out." Does anyone have any tips or anything they could recommend?
You can show emotions with thoughts, actions, and dialogue. For example, if he/she meets someone who makes them angry, the character could think things like, 'Stay, calm, he'll leave soon' or 'How can she stand there and smile like nothing happened?'
You can also show how other characters react to you. If you're sad, they give you a hug, if you're angry they take a step back or act defensively.
