How did you find meaning in life?

If you don't like your major then change it. Go to the nearest childrens hospital and volunteer for a day. I am sure the little ones who are dying to live would make you understand life does have meaning. to be truly happy you must forget about yourself . It also sounds like you need something to love maybe a dog, bird, be a big sister. Maybe too much is handed to you and you don't have much to strive for I don't know sweetie but your life is important and does have meaning don't let it go to waste
