Sometimes, the healing we need takes place merely by having space.
There's something to be said of the phrase, "Absence makes the heart grow fonder."
Under some circumstances, this can understandably be a painful experience; in situations where we're having a dispute of some sort, some distance and some time is almost always a good idea. When cooler heads prevail, we're far more capable of finding a workable solution.
Most of us have encountered people who are committed to being unwholesome and committed to creating bad karma for themselves; sometimes, we're even involved closely with them (as in family or friends).
Yet what I've found, and likely what you've found, is that the people who irritate us the most can also be great sources of joy for us when we've formed the proper boundaries and had distance from them. You may find yourself unable to live with another person but also find that you delight in their company around family vacations and holidays.
(Note: I'll always come back around to the concept of setting boundaries. A lack of healthy boundaries is probably one of the biggest issues I see happening in American culture in the present day.)
Meditation is also a way of forming space; meditation gives us a bit of distance from our ordinary mind and ordinary way of processing things and ordinary life and allows us to refresh a bit.
Never underestimate the benefit of having some distance from the things that make you miserable.
