It seems to me your strategy should involve the following, among other things:
1. A reality check. You cannot improve without materials. New materials, as well as full mastery of what you've got. You need to invest in yourself.
Please read that again: YOU NEED TO INVEST IN YOURSELF, which means you WILL have to get more materials, especially verbal (your post is full of grammatical mistakes, so its not suprising you're challenged by the verbal.)
The VERBAL is totally doable, but you need to PICK a strategy (there are numerous ones out there: Test Prep New York (us), Princeton Review, Veritas, Manhattan GMAT, Kaplan. And DO it!
First, learn HOW to do it, then use the GMAC tests as PRACTICE of what you learned.
2. Bag the "I can't be optimistic about myself."
If you aren't, who will be?
Work on the material and yourself. If you go into the test not feeling optimistic or confident, it will affect your score. Again, if you're not willing to invest in the minimal resources, then I'm not sure why you're bothering applying in the first place (Where are you that you don't have access to the minimal material? Libraries and bookstores, and amazon.com mails all over the world...).
Business school is an investment of resources and time - - if you're unwilling to put time and money into your path of getting there, you're likely going to be struggling through the entire process.
Sorry about the tough love. Just the way I see it.
Good Luck!
