Cholestrol. Family history also. helpa!

I had severly high cholestrol of ldl 188 in march 2020 , and on march 2021 my ldl was 55 , i used no statin or anything controlled my weight from95-72 ans just an cholestrol lowering oriented diet and my lipi profile came.normal but after a year at start i was not regular though first 3 months had no effect at all ldl was 170 but after 6 months and 9 months ldl decreased exponentially, but my concern is which is giving me anxiety that is the damage already done i had cholestrol in me for 1 year they for sure have done harm as i have anger issue my bp would have rise cause inflammation, although i had 2 echos and ecg with gap of 1 year which were normal but i am still concerned can at any time i would get an heart attack because 1 year with high cholestrol, it is scary, should i get an ct angiogram too see if its all f9 or should i consult a psychiatric as i am going paranoid, i dont have any family history also.
