Children don't come with instructions and many parents do what they think is right. Society tells parents that physical punishment makes children more obedient, but studies show the exact opposite to be true. So forgive them for not knowing any better. Your sister may be taking after your parents in disrespecting you as a person. In order to prevent this from continuing, you'll need to have a long conversation with them. I know everyone's busy with their own thing, so you may need to write a letter, but a family discussion would be best. There are serious issues to discuss. For example, do they know you are depressed and suicidal? Do you know they love you? Do they know physical punishment has been shown to create disobedience and abuse? Do you know why they behave the way they do? These are all questions only answered through communication as a family.

If you are scared to do this, start with a friend and talk with them. Once you have said some things out loud, it becomes easier to say them out loud again. If this still doesn't work, consider calling a suicide hotline. Trained counselors can give you alternate advice. In the mean time, focus on things that reduce stress and bring you happiness, such as music, games, or making something. Setting short term goals and working toward them can also help, just as completing an animation can feel like an accomplishment. Those positive feelings can help give you courage as well and, if you choose communication, courage will be helpful.

I do not know how bad your situation is but whatever is happening, you NEED to call a proffesuonnal like some organisation who helps with depression.

Kil.ling yourself is not the answer, think about all the great stuff you'll be able to do when your family won't be living with you anymore, all the things you won't have experienced... You cannot give up!

Please don't kill yourself. Stay strong and make little goals to guide you towards independence from family. My boyfriend had told me we are given only enough hardships for us to handle and they'll make us grow
