Yes, practicing mindfulness can be a bad idea.
When one practices mindfulness, he opens his eyes and comes to see more and more things that were previously unnoticed. That is the reason why beginners tend to think "When I sit on a cushion, there's a fireworks of thoughts, images, etc. coming to my mind. It seems like an endless waterfall of thoughts, etc.". This is a mistaken conception, though, since these "fireworks" were actually already present, but merely unnoticed. Thus, cultivating mindfulness (along with vigilance) helps one understand better what delusions are the master of him. He also comes to feel that he is enslaved by these afflictions (which is a necessary step in Dharma practice, since it leads to generate the wish to abandon afflictions, recognizing them as the origins of suffering).
All this is painful and stirs the mind quiet a lot. Through cultivating mindfulness, we exhume "demons" that we might not be able to face yet, or to understand. We might shed the light on things we are not able to look at yet. That is one of the reason it is necessary to rely to a teacher who gives you practical (and boring) exercises and with whom you have interview every so often. Moreover, opening one's eyes is necessary but not sufficient. We have to change what we pay attention to and the way we pay attention to them (these are usually part of the exercises). This is difficult because karma drives us to pay attention to always the same things that feed our deluded mind more and more. In addition to relying on a teacher, one must study, because by way of studying the teachings of the Buddha, you will come to know what to pay attention to, where to look, and how.

Mindfulness isn't about self-diagnosis but it can easily lead to self-criticism if one isn't careful.
It is about being present and objectively being aware of what it is without judgment.
This is rarely a bad thing.
Even if you are out partying, you can be mindful of your wacky dance moves and so long as you do this correctly (without judgment) it will not necessarily interfere with your ability to have a good time.
Even with the most worldly examples, everything is in its right place when mindfulness is practiced correctly: making love, playing video games, eating, etc. It can be nice to stop even in the midst of enjoyment to be detachedly mindful... it often produces great insights.
Moresoover, the non-worldly activities are helped through mindfulness as well.
The problem is when people use mindfulness to stack thoughts on top of thoughts due to self-judgment. Mindfulness is not about that.
If one enters a state where one cannot stop one's thoughts and one cannot calm oneself, one should practice samatha not vipassana (mindfulness)... or just try to force oneself to go to sleep.
Proper mindfulness always leads to an effective course of action but one should always hold more important an attitude of self-acceptance and non-attachment as the heart of mindfulness.

Look up satta bojjhaṅgā or 7 Factors of Enlightenment.
From Aggi Sutta, example of the wrong time to cultivate 3 of 7 Factors of Enlightenment (tranquillity, concentration, equanimity)
At such times, monks, as the mind is sluggish, that is the wrong time to cultivate the enlightenment-factor of tranquillity, the enlightenment-factor of concentration, the enlightenment-factor of equanimity. What is the reason? A sluggish mind is hard to arouse by these factors.
