Where can I escape, when there is nowhere to

There are times where I have this feeling in my chest, when reality falls down on me. Moments of my life where I know I need to go away, when I feel that I dont belong in this place, in this moment, and that I have to go now there... And the situation is, that I dont know where is "there"

I have a good life, good health, good options, overall, I have a life ahead of me, and I am aware. I often think that I want to disappear, but I have very clear this it is not a situation where I wish to un alive myself, or where I even want to entertain such idea, because I honestly love life, and everything it has given to me.

But then, what is that feeling I dont seek a higher purpose, nor do I think that my life is being wasted. But then again, what is that feeling, where I feel the need to disappear, to escale, but I dont have an idea about where.

If anyone can say anything, I would like to hear it
