Sometimes, you just have to live. That's all. You don't have to be hard on yourself when you feel like falling apart. Sometimes it's okay to just wake up, eat meals, and live. I know it's hard when you've already lost interest in everything that the world could offer you, but please hang in there.
Quit thinking about giving up on yourself because you are the only one who can help yourself now. No matter what you're going through, promise yourself that you will survive it. Because the truth is, you need yourself the most right now.
