Thank you for your response, Rougeleader. As this is something I've struggled with for so long, I would like to try and expand to see if it is indeed what you are referring to as well. I struggle to explain it elegantly, so please do endure my clumsy attempt

So many times I have been in agony, depression, anxiety, and I've just wanted it to end. So often I've been somewhere where everyone was having fun, but I quietly left with feeling like it was so empty. So often I've been in conversation with others, and have felt uninspired. As if we were standing around a pile of shit, obsessing over its qualities.
The heart and mind ache for something better. Since I was young, my sister and I have spoken about not feeling like we belong here. About longing to go "Home"--even though we didn't really know what that meant.
I've learned how to make the best of life. But it will not change how weary I am of what I've come to consider a quasi-hellplane. I can still appreciate life, but this is only because I sometimes see, feel, and experience the ecstatic source of it all. Maybe it's a kundalini rush from a song or situation of significance. Maybe it's a sudden rise of euphoria stimulated by an insight.
Perhaps the burden is that of identity? Or it is that of the material/physicality of the human realm? I believe one of these what was being left behind when I finally felt free of it. It was both terrifying, profound, and INTENSELY blissful.
And maybe it is just the nature of the human realm. But that does not mean I will stop when I ascend. I want to ensure I never experience this burden ever again.
Again, forgive me for the clumsy response here. I am, for some reason, struggling to write well.
