Damn, I really cannot advise you on any other resources as I have not used any but
E gmat.
I am trying to think here what you can do to increase your scores.
Maybe my score got better because I have a quant background and egmat was enough for the verbal part.
If quant is your weak spot, I have heard that TTP course is really comprehensive.
Now, if you feel that you have developed a blockage with GMAT (I developed one myself after two attempts got disrupted by glitches in the GMAT system, it was traumatic), maybe consider taking the GRE.
It can really happen that the more you fail the more you feel you will keep failing and this cycle needs to be broken in order for anything to change.
I am sorry I dont have any other advises for you!!
I really hope you can go past this awful phase called gmat study and never have to sit for this test again.
