There's nothing to practice. Socionics just is. It reminds you that no matter what you do or go through, you always are just yourself. You got over your relationship conflicts not via studying socionics, but because you gained a healthier and more realistic perspective of yourself.

It reminds us that people like us for subjective reasons, that if we're clearly not being understood who we are at the core level to just move on. But in day to day operations, it's not about being understood it's about getting a job done. Of course if you have a middle-class profession like psychology you might not understand that as your job is about walking in-between worlds...
