My best advice:
Temet Nosce
Explore about yourself.
Write every time you feel that you have something in your chest.
It also helps me a lot to have a notebook with extracts of the best texts I have read with own annotations of feelings about them.
Thanks for sharing what works for you, @hijosdelhombre. Journaling is a great way to understand yourself better and to process the your feelings, especially if you're the type of person to ignore or bottle up your feelings.
