It feels like I have no will of my own

Intro ; 18M, I'm sorry I'm new here and I don't really know how to word it out because English is my second language and it may require you to know a bit of my past.

Past : Since a young age I have always tried my best to be a obedient son and I used to fear my parents a lot due to which I mainly focused on study up until I graduated from highschool and never stepped outside for anything other than things I must do at any point in life so far. Mostly because, my parents did not let me hang out with my school friends that lived near me and I only stepped outside to play if my cousins(a joint family) invited me.

Problem : I feel like a robot at times. Unable to do something or anything unless someone tells me the exact way to do it down to the tiniest bits of details.(For example - if someone told me to place a thing somewhere, I often worry if I should keep it vertically , horizontally or some other ways to place things and end up inquiring friends or family about how to place it). It feels like I just freeze between when in those moments.

Help : I want to know what it is that makes me so anxious or overthinking ? I don't know the right term and also need guidance.

Thank you for reading so far and I would appreciate your response.
