When you are depressed you can often feel worthless, you look at your life and the lives of those around you and see that you don't matter, and often when you are depressed you withdraw so completely that you have already taken yourself out of the world so taking that last step and ending it all wouldn't make much of a difference. If you really feel this way then change it; depression can mess with your mind a lot, but it cant completely obscure cold hard facts, so do something so important that you can always point at it and say, "I feel worthless, but I did this, and that has real worth". When I was first depressed at university, I thought of killing myself on a daily basis and withdrew almost completely, I even made my councilor cry just by describing my day (I still feel more proud of that than I should) but through all this my sister was suffering at home from a father who, well, lets be honest, bullied and beat her all the time. Because my dad was so unfit, my mum had checked out mentally and my brother is a self-absorbed **** it fell to me to look after my sister every time she felt down or needed help, even though I was going through hell myself. This was so emotionally draining and she continued to lean on me for the next 7 years, but as difficult as it was to carry my problems and hers, every time I felt like the world would be a better place if I died, I could think of my sister and say "no, if I died she would have no one to help, I am needed here" that thought alone is so incredibly valuable for someone going through depression, the knowledge that though you may not feel it, you are needed and you are valuable. So if you feel worthless, if the whole world feels like shit no matter what and you plan to kill yourself anyway, then it cant hurt to use your life a little before its over and make a difference. Damn this world and damn everyone in it, but before you go you will help just 1 person who truly needs it, 1 person who means something, ANYTHING to you, before you end your life, save theirs, and then realize what you just did, you have the power to change things, no matter how much it hurts you can still make a difference, even if its just by being there for someone in need. I am incredibly proud of my sister and my part in her life and it continues to be a crutch I lean on, whenever I feel bad I help her with something and I feel so much more valuable and validated because I have made a difference to someone who matters, and that can be something you can rely on too, find someone who needs help and help them, if you have given up on your life then spend your energies, no matter how limited on theirs, and then you will earn your value, you will not be worthless, no matter what depression may make you think you will know the truth every time you see that person do well. They will be the proof of your worth. I know this isnt nearly as powerful or inspirational as it sounded in my head but it really is such a powerful tool for overcoming that feeling of worthlessness, for proving to everyone, especially yourself that you do matter, and with the world as self centered as it is, all so many people need is for someone to simply try.
