Traumadumping isn't just telling your friends about your problems, it's using them as a sole emotional crutch and putting them in a position emotionally that they aren't equipped to handle, while a therapist is equipped to handle it and in fact that is their job. Therapists shouldn't be so expensive imo they should be included in health care (which should be universal everywhere in a better world just sayin), and going to a therapist doesn't mean you can't share your woes with your friends but it can teach you healthier ways to do so.
