I dont know anymore if its therapy abuse or me not taking responsibility. Pls someone give me some input/viewpoints.

so, i am constantly angry that I didnt receive proper trauma diagnosis, even if I myself said that was what was wrong with me. For many years I didnt feel like I could take it easy on myself nor understand why I didnt accomplish anything. Once I got the trauma diagnosis I understood more of myself and why I seem incapable of managing normal life. I got to learn some great coping skills and my life is a lot more manageable. I finished my bachelor's degree and worked for some time. Im back in therapy because there was a lot to treat (severe trauma while very young). I am so resentful I didnt get proper help at a younger age. I cant stop thinking that I would function a lot better with the right treatment (I was 40 once I was diagnosed with the right trauma dx). Am I not taking responsibility? In addition; I am from a very disadvantaged background. I feel like the more privileged background the better help one gets (I saw a researcher in my country say as much, so its not something Im imagining).
