Well said, being too empathetic, a worrier and generally caring too much is a grave mistake (tho' I would not worry too much about this as it far from uncommon).

Look around - I am pretty sure you will find most people don't care/worry/empathise that much and they seem to be perfectly content with this. There is a lesson here.

I expect if you probe you will find your more extreme concerns and worries don't much resonate with others and if they don't care why should you? In any case there is little that one can do about most things so you just have to do what you can, and let it go at that.
