Is my lack of skills in science and mathematics due to genetics?

One long but precise question.Basically i was pursuing a degree in the social sciences and was doing well, but i decided to to take another road in the trip and study biotechnology. Unfortunately this is not going well as i had hoped. I am barely ping in every cl and i had to drop one of the five which was physics as i could barely understand the subject. I have come to realize i do not think like a mathematician or a scientist clearly their way of thought is rather different than mine. I now know that social sciences was where i belong (as i am great in writing). So is my conclusion regarding my brain correct, could it be the way my brain functions. I ask this because i would like to be free from all the stress, i like to think that i really and in all honesty gave it my best shot but it seems undoubtedly that science is not the career of my type even though i do wish to learn about the natural world. If you are a person with experience, or a professional who is reading my short story i do welcome you to share your opinion as it would help me cope with the challenges i am facing in university in biotechnology. I posted this note in the science section because i want an answer that is convincing and has logic to it.
