Divide and

What do I do with my life? I'm so afraid..I'm so afraid that I won't be able to make it in life. I feel like I cannot do anything. I don't have the capabilities of doing something great. In high school, it was so easy. But now everything is different. I mean, I'm getting A's so far, but I don't know. I just want to help people..But I feel like I am not smart enough to...do it..
