Why is life hard?

Why is life hard? Why cant we have all the money in the world? Why is half the world suffering? How come we cant stop global warming? Why is life so hard? I always think about these questions, but the silly thing is that i dont even have the answers for them. Well I dont know what im trying to say. I just want to know why is life so difficult!?! Why does god hate us? Well he doesnt hate us, its just that if god created us and he wants us to live, then how come he creates things such as earthquakes and tornado's and other stuff, I feel that a lot has changed since a long time ago. Apparently Global Warming is getting bigger... :/ And I WANT IT TO STOP! Were all gunna die D= well acutally not literally, well maybe when were in our 80's or 90's if we can live that long. How come, when you go to a school and when you make so much friends, and when you grow up and make more, it's like others betray you, and it's like you dont trust them anymore, but i dont get it? Finding friends Forgetting Friends making new friends, it's difficult acutally. And how come parents get divorced? But dont they love eachother? Cuz if they do then why would they get divorced, if you never liked them then you shudn't have married them. But sometimes in the long run when they get married the 2 people are livingin happiness and joy but after sometimes their relationship grows apart. :( There's a lot of things to worry about, i try not to :P
