How to start?

Hi! I'm currently giving SSC. The thing is I messed up. How? I did bad on general math (like 16 mark gese). And now there's a high chance I won't get GPA 5 on ssc. Because after math exam the butterfly effect took place and i ended up doing pretty bad on the next two exams as well. It broke whatever confidence I had and messed up my mental health completely. Here's the example I've been crying non-stop, my hands have been shaking constantly and some other stuff as well. Let's just say I'm at the verge of complete mental breakdown.

You might say that, it's not a big deal I know that as well. However it has been made into a big deal by the people around me. Everyone thinks that I'm some kind of perfect and ideal student. Which I'm not. I'm just your average Joe. Now the reason everyone thinks that is because I just happen to have more practical knowledge compared to people of my age(which is because I was practically raised by the internet) and I just happen to be present when needed. Now the expectations from me are high because my second older sibling was the high achiever and the one who showed everyone their efforts. They also got a GPA 5 and a "Golden A plus " in SSC. And I just know I won't be getting any of that. Now the only way to justify my result is by earning money before the results are out. Which is not that much time only like 2 to 3 months. I wanted to start a small business by selling crocheted key chains I know crocheting well. But it will take a long time to get anything in return. So I decide to do some freelance work I know excel and have a (kinda solid?) foundation on Phython which I'm also planning to work on after the exams are finished. Now you can say I'm kinda desperate to earn money because I also have plans of studying abroad. But my family won't be able to handle such huge financial burdens because my other sibling will likely start their masters this year and they are currently studying in a really expensive university.

Now after all of this chitchats here is my plan:

After my examination I'm gonna treat the 1st month as the "learning and improving stage" then I wanna start earning from the second of third month.

Because I plan to attend SAT on my first year of inter and if I do well on that then I'll be using that score for applying abroad if not then I'll attend SAT a second time. Now it all requires a huge sum that will put a huge burden on my family as our sole earner (my father) has retired and a huge sum is also required for my sibling.

Now the advice I need is where to start from which will let me earn money within next 2 to 3 months.
