Why am I only aware of this body-mind?

This has been the biggest obstacle, yes sensations, emotions and thoughts arise and I am aware of them but why am I aware of only this body-mind?

In this way, the only thing real is the sensations that are happening now and ultimately even the concept of other people existing only exists in my mind? aside from when you see others, since there is no line seperating the one who sees from what is seen.

I know this is called solipcism which I know not to be true but its just this thing that makes me doubt

what do you guys think?
