Hi

Suicide can never be an option dear, leave being right alone. I know you are brave and a fighter and  fighters never give up and fight till their last breath.

Think about your parents after you are gone, who will take their care? They need you, you need to be here.

What should you do?

Fight with your problems, if you are not good at studies, take the help of your teachers, ask them questions whenever you are not able to understand things, also it's 21st century everything is available online in easy to understand language, you can even take the help of videos available on YouTube by several teachers to understand concepts if your teacher is not helping you in  it.

Also,

Things will not change overnight, it will take time and soon you will be good at studies and can achieve whatever your dreams are. Remember no one when is born intelligent, it's all hardwork, consistency, and a lot of practice.

You can even look for alternate opportunities . For example, if you have  good writing skills then you can work as a freelance writer or you can even follow your own passion and make a career in it like if you enjoy travelling then you can be a travel blogger/vlogger etc.

At last, I would say that always remember your parents lov e is unconditional whether you are good at studies or not. So, give up your thought of attempting suic ide.

In case,

If you feel like talking to someone then you can call on 1-800-273-8255 which is a helpline number issued by government of India for prevention of suici de. And don't worry your call will be kept confidential.
