Cholesterol fears.

19M 175lb 6ft 1

Had a test after I got home from college, and the results came in:

Total Cholesterol: 226

LDL:152

HDL: 61

Triglycerides: 75

VLDL: 13

I've finished my 2nd year at college, and I def think it was the schools meal plan (it was all fried stuff, and definitely not with olive oil) + ashamingly stress eating oreos after reading "oh no cholesterol". I didn't really gain weight so i thought i was good. Coupled with health anxiety, ive been worrying. Am I screwed? Can I fix this with a proper diet?

Ive tried to eliminate almost all saturated fat, add more fiber to my diet, my grandma (i live with her) cooks healthy enough foods. Rarely fried, cooking with olive oil (Italian household), I try and keep as active as possible. Im 19, im afraid I've instilled a problem for life so soon.
