I need to earn 2 lakh in an year to help my family.

Hi, I'm a 15 year old girl, with decent drawing as a skill, I'm willing to spend as much time as I can to learn any skill that can help me earn and reach my goal, I only have a phone and an ipad right now. I want to earn 2 lakh in an year so I can move with my brother and mother, my father died 3 years ago, and ever since we've been struggling with money, whatever money we get, my stepdad (who even my mother hates atp) takes from us and it's very hard to save or use the money we have saved, because he keeps track of everything we do, divorcing him is not an easy thing to do because my father's side of family can't know about it or whatever little child support we get from which we eat our usual food will stop coming. If my stepdad didn't take majority of the money we get from the child support, we would live very happily, it's only him that spends endlessly without a care for our household expenses. We only have money for the basics, anything more is too much, the condition we are in right now is destroying our health as we can't even buy normal medicines or do simple things, going out is also not possible. I want to save up money so we can move without him knowing, so we can live normally and stop suffering like this, I'm willing to work as hard as I can, I love my mother so much and can't see her struggling mentally and physically like this everyday. What are some skills I can learn from which earning is possible? I would like to get some advice and get tips please. Edit: our life is being impacted so much that we don't Even go to school anymore (not an important point but I need to describe my situation properly) but that doesn't bother me, if we leave, we might be able to save enough to go to school.
