can't stop thinking how things started

I am very interested in art and cinema, and those stuff, I have thought about studying film, but I can not stop thinking about ow I gained the interest, it is from the internet, because it only source I am able to take information from, can't expect much from 3rd world country, but I am afraid it all started from bad stimulation, like from a bad video, or a bad article, and I gained good English knowledge from internet too, like when I was young I watched every s**it came into my feed, read everything, or it is just I have a good brain to comprehend a new language, I first watched thing in my native lang, but then it changed, I am really afraid about this chain reaction for some reason, like things are not real? I keep saying to myself, it does not matter how I gained the interest, what matters is now I have the interest and I am working towards it
