failing in intensity phase (5x5)

[Sub-Zero]

i failed on the intensity portion...i got 2 (and i guess a half) reps instead of the 3.

i think it was more of a mental issue than a strength issue, but anyway, how do i go about dealing with this

do i
1) do the same weight next week and get 3
2) take off five pounds and try
3) add 5 pounds to the weight(instead of usual greater increases), even though i failed, so this way i increase a little bit, without going too far ahead
