Hey guys ive been pretty depressed lately (ive been crying whenever nobody is around) My sister been cutting herself and she almost overdosed herself,and shes been taking out her anger on me and my mother,my mothers becoming really stressed an my mother hardly has any money to buy us food. . . .i just really need some help right now to cheer me up a bit

that is harsh. I only know one way to not be depressed. I don't know if it will work on you, but it works for me. want to let some steam out? pour all of your anger in games, I prefer you pour it on shooting games. want to escape from your current reality? watch something that you have never watched before, I prefer you watch something that will hit you inside and make you feel what really is happening because it might relate to you. want to help your family? first, work to help earning money, it depends on whether you can work at your age or not, doesn't matter if it's part time job or full time. second talk to your mother about what you feel right now, I mean your mother should be in control of your sister. third, you didn't mention a father, so i guess i want talk about it. so here's the actual third, forget all i said, and follow what you really want to do to help your family. I told you it worked on me, but might not work with you, because the only one who can change someone's fate is themselves. It's either you walk the path of light, the path of darkness, or both of the paths at the same time.

Changing your fate is a tricky issue (with all due respect, ZAK) that has too many variables to be considered a sole person's duty. For instance, if capitalism dictates no money means no food and nobody is willing to exchange your goods or services for money: where will you get food?
Under the powers that be, you should starve!

Or you could steal food. Even then, you could get prosecuted by the powers that (probably shouldn't) be or something similar. Even with all the willpower in the world, if you're fighting against an overwhelming majority, your fate is pretty stacked against you!

I don't mean to try and discourage you from trying anything though. By all means you should try!
It might be worth asking around a bit more locally (food banks, maybe?) or giving some more information so other Dollars can do a little digging and (maybe) get back to you with more help.

There are nice people out there. I remember someone asking me if I could buy a reduced load of bread for them (it was about $0.50) because they didn't have any money on them, and of course I did! I couldn't be happy knowing someone else was going hungry, and that should be constant across most people.

What's important is reaching out and letting people know. Good things will only happen once the message spreads, I believe.

I tend to watch series and movies with an overall happy or ridiculous setting when I feel depressed. However, if it hits hard, taking a trip to the countryside, running through forests, shouting and letting yourself down on a nice glade is almost always relaxing.
Thaz much for general information, I would talk to my sister, tell her how much she means to me and that i will always be there, that I need her and all that stuff I am feeling when thinking of her hurting herself. Of course I do not know your relation, I guess this ould not work if you do not get along, but even then, some honest and couraging words might change something for her. Do not tell her how stupid or bad it is to cut oneself, she knows, that is part of the reason she is doing it.
And lastly for your mother, if you think you are able to manage it, get a part-time job. Working cleans my mind and lets me escape from the current state of affairs and of course you would help her in terms of finances. If you are unable to find or take on a job, help out with housework. Again, I do not know about your relationship, but from experience I can say that a child's support means a lot to a mother.

All of this expects you to be strong, so be brave and try to help the ones close to you, supporting them in even the slightest way can change a lot.

Thankyou all so much guys your advice has really helped me i knew i could trust you all

Glad we were able to help you, we will always be there for you!
