Ya know what?

If you've been there for 8 months, and you're still having that much trouble, go back to an earlier save point. Then go around drawing magic, and gain AP to let your GFs learn their abilities. Plus, find any extra GFs.

And if you don't have any earlier save games (because maybe during the 8 months you erased them to make room for other game files), start the game over again. From the Beginning.

This time, pay attention to the junctioning system, and make sure you gain as much AP as possible, and make sure your GFs learn the best abilities first. Draw magic from enemies ALL THE TIME. Whenever you fight an enemy, check to see what you can draw, and if there's something there that you haven't drawn before, draw 100 of it for each person. This will take a little more time in the beginning, but will save you time in the end. As well, when you do this, you will find that you will be able to draw and recieve extra GFs from certain bosses, like carbuncle, siren, pandemona, etc.

As well, do the sidequests, and get GFs like Tonberry, Bahamut, and Eden. All this will make the game much easier, and much more enjoyable.

As well, you will OWN Adel, and just about everyone else. The last time I fought her (which was just the other day), I was so powerful I had to be careful not to kill her too quick, so I could mug that Samantha Soul from her.
