Hello there,
Don't worry everything will be fine. Please don't lose hope. Stay strong, and stay focused. You can achieve anything if you are strong and confident from within. Don't let other people's view to affect your life this way. Keep yourself motivated. It is better if you can make time to do meditation for atleast half an hour everyday. You will feel much relaxed and positive.

Coming to your SBI exams, yes you can definitely show your worth to the world. Start preparing yourself. Know your syllabus, and try completing your syllabus keeping time for revision. Solve the previous year question papers as well. These give you an idea of the trending questions.

Please be confident with yourself.
Hope this answer helps you.
Good luck!!
