how does it feel to overdose by medicine?

Its been getting hard to hold back myself in our family's problems. My mom and dad only cares about work and they decided to rely on me to take care of my 4 younger siblings, I'm already at grade 11, i can't hardly do study and make activities. Every time, i told them about how i feel, they will put it aside and compare how they lived in the past and they will tell me its not that hard.

I started taking care of my siblings since i was 7 years old, i can't even remember what was my childhood memories. The only thing i remember was taking care of my siblings. They would always compare, body shame me, and told me that i'm weak. I can't take it anymore and was thinking to use Biogesic as my freedom, I'm scared but I'm determine to do it.

they told me that the only thing i did was to take care of our youngest, like cleaning him and cleaning his bottles. They don't even care, I'm the one who always get my younger 2 siblings from school, even decided to help their assignment even though i have a lot of activities to finish too.

I live in a different house, but i can only stay here when I'm going to sleep or taking a rest for 3 hours (which is not enough, cause i have 6 activities that needs to past at the same deadline) even in weekends, i don't have any rest. They recommended me to do the activities in their house, but i can't focus because of the noises and my siblings.

Me and my mom had an argument today, and the only thing she said is comparing how she live and how i live. I'm so angry, that i want to run away from home, but I'm a minor (17 years old). Even told them they shouldn't have kids if they can't even take care of their other kids. They always relied and relied to me, i can't really take it anymore. Been thinking of doing it since i was 12 years old, but kept going cause i want to leave. But, i guess my mind doesn't need it anymore.

I'm from the Philippines, i don't know how to leave and they teach me to rely on them too much. So i don't know what to do
