Yes, you can change your life.  I've done it.  Keep in mind that it doesn't happen overnight because you didn't get where you're at overnight.  I recommend seeking the professional help of a therapist, psychologist, or psychiatrist.  If you're willing to work hard and make it a priority to change your life, you can.

Try it out with just one of your goals.  Write one of your goals in one column and the steps you need to take to achieve that goal in another column on separate lines.  Be specific.  If you start coming up with reasons why you can’t achieve each step toward your goal, list those reasons in another column next to the step to which it applies.

Then, write your beliefs that reflect those reasons and start thinking about how you need to change your beliefs to achieve your goal.  What should you believe about your destiny?  Remember, your destiny begins with what you believe.

Believe.  Receive.  Achieve.
