I am not a chemistry major, but I definitely want to be one and I'll try my best to give you any advice as a high school student aspiring to study chemistry later on.
First of all, if you love chemistry, you shouldn't be scared about the competition surrounding you. Once you love anything and truly are devoted to the subject matter, you become fearless; you realize that people around you don't matter as much as your knowledge and hard work does. Yes, chemistry is a gigantic field, but other people should not stop you from doing what you really enjoy. You might not be the best now, but you have the opportunity to improve yourself. Try studying by yourself; if you really enjoy chem, this should be a hobby whenever you are free.
I will have taken chemistry classes for 3.5 credits (.5 credit per semester) at the end of this year. Until just last month, I tried to avoid hybridization as well; I hated it because it was hard for me to visualize. Then, I decided that I will face my fear and try to overcome the intimidation factor. I knew that I would eventually need to understand this and I couldn't let it take the best of me. Yes, the hybridization isn't the easiest part of chemistry, but that doesn't mean that you can't learn it. Spend some time on it and most importantly be patient. I can't tell you how important this is when studying any difficult or uninteresting field. If you believe you can do it, you will be able to get to the top. But, you need to put in the effort to do so, which means working extra-time on chemistry.
