I know where you are right now because I have been there too, I know how it feels to be so sad for so long that you can't imagine being happy again, to be so sad for so long that you stop trying to be happy again and so you just feed the sadness, just try to give it what it wants in the hope that it will be content enough to spare you, but feeding it only helps it grow. You have to starve it out. You have to lock it up, have to tell it "no", have to fight it. It will claw at the back of your eyelids, it will moan and howl so loud that you cannot hear your own thoughts, you will ache because it is aching and you and it are one but you have to remind yourself that it is created entirely of you, but only a portion of you is made of it. You have to make it shrink. It will not be easy. There will be days when you give in, when you feel bad for it, withering away, and so you throw it scraps of food under the table but there will also be days when it is silent. It will have grown so weak that it can no longer pound on the door, it will lie still there in the dark and you will forget about it, if only for a moment, and you have to hold onto that. There will be good days, days when you think to yourself "this is how happy people feel on a regular basis," days that remind you why you are fighting this beast in the first place and the next day may be bad again, you may not hear that silence again for weeks but when you cannot see an end to this torture, you have to remind yourself of the good days, you have to keep them tucked underneath your pillow and reminisce about the way walking felt easy for a day before you go to bed, you have to keep telling yourself that although this is an uphill battle, it will be so much easier on the way down the other side and the view from the mountaintop is breathtaking. You have to convince yourself that you want that mountaintop, have to tell yourself that the good days are worth the fight, that the sadness will not last forever, that you are not made of darkness although it is made of you. You have to starve it out; it is so much easier to live when you only have to feed yourself.
