be more sympathetic

I don’t think I am self involved.. I am just gaurded and seperate from things.. I don’t let “petty” things affect me and I am quick to rationalize. I process and move on to more “important” things. What I realized is, as this works in my mind, it is not the same for those around me and I always come off as cold and uncaring. I don’t know how to be more sympathetic.. either it’s genuine or it’s not.. and I don’t know what it would take for me to care the way ppl want me to care…
