I just don't get it

I don't get it. I don't know why. This is hard, real hard. Some days I feel on top of the world while some days I feel like I do now. It's not that I feel bad and it's not that I'm weak, that couldn't be further from the truth. It certainly isn't that I don't have faith in God because believe me, I do. I just feel like I don't get it. Does that make sense? I know everyone must feel like that at some point in their life. I started school today. It's great to be back! But I just don't get it. Why do I have to repeat my senior year? Why couldn't I have graduated with my class. I don't feel bad about coming back but I just don't get it. Why God? I know this is all part of your plan but sometimes I question you. I'm sorry for this. If its part of your will please help me understand because I just don't get it.
