Well it's a mandatory subject as of now. Once, you've crossed 10th Std you can opt for other subjects.
Math has always been a weak point for me too. Take the help of your teacher so that you do not flunk, and get a better hang of the concepts. Think of it this way, just another year of math. I studied maths till 10th grade and was evidently unfamiliar with concepts taught in +2. In the first year of engineering however, I had to deal with maths and I worked so hard I topped my batch. So if I can do it, so can you! Keep practicing, take the help of your friends and teacher. All the best 😊
Also, you're way too young to be depressed for studies! Just work hard enough so that you do not flunk. You can do exceptionally well in other subjects so that your overall grades aren't affected. These are the days you'll remember and miss in the future. Don't be too stressed about studies, you'll do just fine. Make the most of this time and enjoy your school days! Everything will be alright
