I felt like my emotions were extremely intense compared to my peers and I acted impulsively during my late teens to early 20s. I was diagnosed with "unspecified personality disorder" with some BPD and OCPD traits.
I realized when I switched my major for the third time as I had no plans or goals while my friends were already done with uni and started working. I was also maturing and getting tired of letting emotions control me and setting me back.
I honestly wished I could find someone to blame my issues but I was extremely mad at myself for letting myself go and it devolved to self loathing. DBT is helping me by being more mindful and acting the opposite what those tell me and I find it helpful so far.
