If all the conflict is wrapped up into one tight little ball where it feeds off itself, then you're probably okay, unless you're writing humor. Hard to throw in humor when there's so much angst. Not impossible, mind you, but a hard sell.
I personally, hate to read books where there's something going on on every single page. I have attended writer's workshops and they're all "conflict on every page" blah, blah, blah. That's great, but some people take that to mean gunfire, and car chases, etc. and it's exhausting. All readers need some downtime, per se, to absorb what the character is going through.
