Fact: I am afraid I wont be able to do it

But, I am going to give it the old college try. College that is. And, this will be a second try. Not that I have ever gone before, but I did apply once a few years back. Unfortunately,  due to tax issues barring financial aid, and my own lack of  "capital" I was unable to enroll. So here I am again, closer than ever before. I have an AWARD on the horizon, the class is showing enrolled and the student ID is in the mail. The reality of the extra work is hitting me and I am now scared to death.
Couple reasons:
a. I wasnt that hot in high school. Let me rephrase-(I was totally HOT ,which was the issue) due to my vanity, partying ways, and boy vision, my grades lacked in a big way.
b. I tend to lose focus on things that dont capture my interest, for example I LOVE history! Could listen to someone lecture on it all day. But math? Not so much, I just cant latch on. The math teet just does not beckon me, therefor, I fail to thrive.
c. This is a problem because I would like to get an Accounting Degree.... Somebody call Alanis - is that considered Irony?
ALSO......
1. I have 4 kids and I work full time. My kids are already completly messy and totally exhaust me, how can I possibly add 2 classes and homework to this mix ?
2. I am not single but my husband works long hours and hardly ever helps around the house anymore leaving me absolutley frustrated and more exhausted.
3.I am lazy. I have said it before. I like to lay around the house, watch movies and vedge in my spare time. Sometimes I can be productive but for the most part I like to just be laaaaazy in my downtime.

So there you have it. I am afraid I wont be able to do it all. What if I have a nervous breakdown ? What if I have to repay the goverment for my grant? What if I am not smart enough ? What if my kids feel neglected?What if all the girls laugh, point, and throw pads at me in the shower? Oh wait, I am going online....but you get my point. I am in need of some prayer. If anyone who reads this has a line to God will you please ask him for some help for me?
I am telling myself it will be fine. I have it in me and must push through in order to obtain a better life for my family. I THINK I CAN. I have to, these 4 kids are going to need college pretty soon and Mama is gonna need a better paycheck. Pray me luck!!!
