I am a vegetarian, and have high blood pressure, high cholesterol and a fatty liver condition?

I am 64 years old, 60 kg weight and I live in Indonesia. What shall I do ? I try already to avoid all fat and oils, I eat no cheese or eggs and take only little skim milk for breakfast.
I am afraid to take cholesterol medication for the rest of my life...
Thanks in advance for your recommendations !
Update: Thank you so much, Sarri, Elly and Hritz for responding to my problem so quickly ! As I live in a smaller town, I do not know whom to ask for advice. I felt quite helpless and alone to solve my medical condition . Your answers do help me !
Update 2: Often doctors here would just say :" what do you want, its your age ! " and they prescribe more cholosterol pills .
Maturnuwun sangat,
