Why is it so difficult?

I'm trying to manage my time but I feel like I'm failing. It's so hard and especially with my personality that strives on being the best. Right now my schedule is:

Monday-Work
Tuesday-School
Wednesday-School and Work
Friday- Work
Saturday- Work

And at the sametime I'm trying to be a great student, a better wife and fulfil my wifely duties, fullfilling my church calling,trying to control my immune system, hoping that I don't have Rhematoid Arthritis (which I should find out soon!), and taking care of Chloe.

It might not seem like a lot but I feel very overwhelmed. I think mostly its because I talk to people who either 1. Their parents pay for everything like school, car, etc. 2. I want to go out and play, but when I do I feel guilty and think I should be studying.

I guess writing this post isn't helping me with my time since in a few minutes I will be taking a midterm and then an hour after that another one=)
