Hi! I have an enormeous grand cross (mixed with T-Square) on fixed signs, but not on angles like you have. Maybe i can help you anyway
Here is my natal chart:

That's a really complex combo, mostly when it's in fixed signs, because you're going to attract to you a lot of circumstances at the same time, creating a huge knot that seems impossible to undo. But when it's in cardinal signs or houses it's not so bad as it gives you willpower and strength.
It often begins in the childhood like said before, so be aware of the unconscious wounds that makes you feel stuck.
The key is to balance the energies between Taurus, Leo, Scorpio and Aqua. I feel it myself: when i focus only on the material things or work to much (Taurean energy), and i don't go to festivals, or have no time with friends (Leo), i feel bad. And when i give to much to Scorpio's stuff and not enough to Aquarian's activity, i feel empty.
Work on yourself. Do meditations, especially work on your chakras to deblock them. Find peace, because if difficulties are coming, you must fight them, only one at a time.
I must say, that the grand cross gives a lot. But you have to choose the words you wanna put after, whether it's ' of difficulties' or ' of power'. All energy is transmutable. Learn to become and alchemist.
Have a nice week
