Love is just something you feel for somebody; one day we'll all feel it.. whether it leads to something good or bad.. sad or joyous. It's up to the person whether they want to show love for someone.. our anxiety builds up in our body to the point where we just don't know how to respond.. It's perfectly normal to wonder what love is, and I hope I helped a little.
