Then it is time to change your life, not end it. Take control. If you live day to day, set some long term goals, go to school, learn new things, start a new career, colenteer to help others. The world is full of posibilities. Just don't sit there.
Also, I know money is tight for you. But I also know people that have money and they aren't happy. I know people that drive expensive cars but they are so stressed out and aren't the nicest people because tehy spend all thier time thinking about money.
Also depression can be caused by diet. Try eating less sugar and junk food and eating healthier. Serriously, diet affects mood. Try it for three days and see if you notice a difference.
And almost everyone goes through periods of depression. But I think oen of my sayings applies here. I say it doesn't matter if you make mistakes, it matters what you do abotu your mistakes. Same here, it doesn't matter that you are depressed, it matters what you do about it.
Another though, your mood is your choice. Nothing is forcing you to be depressed. I know peopel say things like, wow that is a lot of things going bad, you must feel depressed. But don't listen to them. Soem people can have a flat tire or have the refridgerator break and say how my life is so bad, or this is such a bad day, wekk, life. Others can have many bad things happy and still be smiling. They know it isn't that big a deal and this too will pass.
So something bad happens, you decide if you want it to ruin your day or not.
I could give mroe advice and go on, but this post is already long.
