Was it easy for Buddha to leave the world behind?

in their religion they leave worldly problems alone and concentrate on becoming spiritually enlightened through meditation,love and nature but this also involves leaving your family and friends because the effect how you deal with ever day problems in your life for instince if your mom dies you most likely will go into a deep state of depression this is why most buddha or orphans who's family gave them up as a child so they could achive sumthin bigger then themselves so think it would be easy to leave behind loved ones
