i want to smash coli-

im sensitive when it comes to relationships,, if it was anything sad like animals dying or a family member who has just died or a sad movie etc. i will not cry but if its anything of relationships (doesn't count in movies, because i dont cry to relationships in movies) like arguing etc. i begin to tremble, be okay then cry/break down and stay traumatised for weeks and recover for weeks
