Any benefits to an all-or-nothing anxiety relief method?

I am trying to figure out if consistently suppressing my anxiety would be better or worse than letting it out in a massive dump such that I am basically "blowing off steam". I would like to know what others have experienced in regard to which method has worked better for them as I am sure that each one can have its potential issues / drawbacks.

I am aware that it might be even better just to take a balanced approach which I have done before, but even that has provided limited or unsatisfactory results, at least to some finite extent.
