High ldl cholesterol. But still scared!

I had my cholesterol 254 with 180 ldl and 180 triglycerides in may end 2021 some doctor told me to start statin but i when i took second advice many told to not start statin at such young age at start diet control and i started diet exercise etc for control but due various personal reasons i got off that regime after like 2 months and was back on my old diet , which was basically junk and mess food , a lot was going on during that time and i was just not able to give time to myself and now again i am scared what i have done doctors told me to reduce my cholesterol in 3 months and its been like 8 months , i am a big time hypochondriac (health anxiety) i know there is no wealth bigger than health but things were not in my control , coming to the point , does having such high cholesterol in my body have scarred(clogged arteries )my body to such extent that whatever i do my life is reduced or there is still time for me to comtrol it , because athough i am back on track , but still scared
