Don't give up. There is a reason why less than half of the applicants pass these exams. They are tough. The material isn't impossible, but each test covers so much ground. You need to find your motivation. WIthout it, i can't see how anyone could put the necessary study hours in, in order to pass the exams. It is definitely an obtainable goal. But you need to apply yourself. Make the most out of your days by coming up with a plan. Finally, study materials. You need them. Consider the expense as an investment. I used Becker, and would not have passed with out them. I tried just using a friends textbooks, but that wasn't effective. You need the lecture to point out which sections are most important, as well as further explain the sections in the text.
In summary
1) Self reflection. Determine if this is what you actually want out of life. You can't go half in.
2) Commit. Invest in the materials. It's an immediate financial burden, but an investment in your future.
3) Organization and scheduling. Determine when you will sit for each part, and then come up with a schedule on how to cover all of the material necessary before sitting.
4) Continue to participate on these forums. You will find that a lot of people are in the same exact boat as you. It is encouraging to know you are not alone.
I have a 2 year old daughter that runs like a maniac around the house. I also have a pregnant wife that is tired and sick all day long. Add that to my already busy work days, and you can easily get discouraged. But, after failing both Reg and FAR, i found my motivation, applied myself, and passed all four parts with in 6 months of each other. You can too. It's overwhelming at first, but 1 test at a time and the passing grades will push you forward to the next part.
Good luck
REG - 77, AUD - 85, BEC - 75, FAR - 80
