WTF is up with my life

I don't even know where to start, everything seems out of place and I don't know what to even do. It all started 4 years back, 8th grade and my whole life just goes boom. My dad loses his job and couldn't find any other job as he's pretty old (aCcorDinG to industry standards he's not fit to be working). My mom, sister and I relocate to our home country so that expenses don't pile up since we didn't have a source of income. Months pass by and I didn't attend school at all. I used to cry myself to sleep thinking if life would be alright. Soon, my parents decide to put me through a school in our home country and I felt kind of okay after that. Life goes and my dad still couldn't get a job and we had pretty much burned through our savings and had almost nothing left. My dad then decides to work a job that didn't pay well but would at least put some food on the table. Things move on and at this point it's just living life paycheck to paycheck. My mum and dad would keep arguing on why we stooped down this low and why my dad had debt so bad that it burnt out his savings. This pretty much became constant. 9th grade goes on with pretty much the same happening and life just didn't seem to get better. 10th grade starts and the Covid-19 pandemic just hit us really hard. We had no source of income. Then my sister started working an online job, that pretty much was the only thing that put food on our table. 10th grade passes by and still nothing got better. 11th grade begins and my mom asks me if I would be willing to work an online job to help my sister and dad out with the expenses. They had to pay my school fees by taking out a loan against some gold my parents owned. I pretty much was okay with it since it would at least reduce the financial burden. This all happened since places were still under lockdown and school was going on through online classes. 7 months pass by and lockdown slowly starts ending and places start opening up. Schools started reopening and I started panicking if I could cope up with both school and work. Anyways I somehow managed to make it work and passed with some okay marks in 11th grade. 12th grade begins, the final year of schooling and for some reason I thought to myself, okay, I have done this once, I'll do this again. That was the biggest mistake, every time there were tests and exams, my marks and grades just kept dropping down. I couldn't focus on school or work properly. It was round this time I found about a videogame and ended up getting into it. It was sort of a getaway from reality for me. So much that, I ended playing the game everyday. My grades became even worse and my parents were disappointed in me and wanted me to do better. At this point I'm helpless and I'm scared on what to do and how to get out of this "pit of darkness". Sometimes I cry myself to sleep thinking if I'm gonna screw up my finals and fail in my exams. My finals are 3 1/2 months away and I seem to be making no progress. I don't what to do, or to whom to reach out to. Financially, my family isn't just able to get back to where we were. The only highlight that came out of my job was that, I was able to pay my own school fees and didn't depend on my parents for it. Just recently my parents had to keep some gold we owned to avail a loan in order to make payments for our insurance. This made the relationship between my parents even worse, my parents are having arguments almost every other day. Looking at all this and then just looking at my friends lives just made me feel even worse. My friends are doing pretty well for themselves and don't deal with problems like these. None of them know about what has been happening at home. I hope that no one ever gets to face a situation like this ever in their lives. God bless! I just needed to get this off my chest.
