If you're a black sheep, there’s just something off about you and that’s just how it is. You may try to deny it, cover it up, ignore it, but it’ll still keep you from being like the rest.
This isn’t something necessarily bad. In nature, there is diversity and also anomalies, and that’s fine. They come with their own set of attributes to make them worthwhile, whether they're obvious or not, and whether we acknowledge them or not. However, the different and the unfamiliar isn’t always met with such understanding and acceptance.
If you are a black sheep, and especially if without any other black sheep in sight, your fears of persecution and ostracization may be founded. Unfortunately.
People are quick to notice or sense when somebody is not like them. And whether they are fully aware of it or not, they then act accordingly. With suspicion, defensiveness, hostility, or worse. They may try to change you or downright banish you.
It makes sense, though. If things are running a certain way, and that’s how they’re comfortable, perceiving anything that deviates as a threat is quite rational. What we’d then have to look for is whether they will be humane enough to make adjustments and adapt so that you will be included or go down the more convenient and 'efficient' route to instead get rid of you or of what makes you you - forcing you to lie to those around you and maybe even to yourself in order to be kept around, if you'll even be kept around at all.
When you are the unusual, it can be confusing. You may battle with thoughts and feelings about inadequacy, struggling to justify your existence and all the trouble it seems to cause everybody else. But you can look at it this way: by merely being, you’re pushing others to mentally and emotionally expand, which is part of what will bring them growth and evolution.
As long as you still watch for the things within you that do require examination, pruning, and polishing, so that you, too, can grow and evolve, standing out shouldn’t be deemed such a problem.
