At some point the past few days, weeks or months, however long you've let it go this time, you've contemplated just leaving everything you know because your attachment has become nonexistent to this life you've been living. You scramble for some emotion that makes you feel like you still belong; a resonance to that old feeling you had at some point. You mentally scrape the sides of your soul to bring up something, but all you feel are the empty holes of emotion that come with knowing all those good memories you used to hold are distant and the relationships with those people are changed or gone. You don't even cry anymore because you've become numb to the feeling of being scared of the emptiness even.
This is for those times, to remind you why you're here and it's important that you're even here.
Keep going. Hold on to that thought of finding that feeling of "this is where I belong, where I feel Home". You remember at least the memory of that, don't you? You're meant to be where you are, whether or not you're feeling it now. There's a reason, and, if not to find something, then to learn. Learn from the hurt, the pain, and the numbness. To hold on to yourself and make it through this life.
Keep going. Those people that wouldn't miss you? They would. And it's hard to think of it now, but just remember how it felt to be in their shoes. To ask yourself: why? How? Since when? You may know, but you also know how well you hide it sometimes. Think of what it would do to the only person who you know wouldn't leave you. Do you really want to do this to them? To disappear physically, but be a resonating thought of why in their minds forever? People will care if you're gone. Even if you wouldn't.
Keep going. You've done this before. You've pulled yourself out of this pit so many times, and you were out. You found who you were. This is to remind you to stay true to who you are, to make you stronger so you don't fall again. You've felt all of this before, and there are a lot of new factors, but this is has been done before. Find your outlet, and lose yourself in other worlds. You've lived a thousand lives, become one of them for however long you have to to make it through the day. That's how you did it before, try it now. If you're strong enough to pull yourself out of that pit once, I know you can do it again.
When you feel the losses and the pain so much you feel nothing, read this. Remember why you have to stay. Remember to be on this course. Exist until you're ready to live. It'll take time, but we'll get through it. Just Keep Going.
