Sometimes it’s hard to explain just what having mental illness means. Sometimes there just aren’t the right words.
Sometimes it’s hard to know just where the illness ends and the real person begins. I have been diagnosed as Bipolar I, and as having Borderline Personality Disorder. These terms do not define me, but they do explain me.
I am not my illness, but I am responsible for keeping tabs on it, for self-monitoring, and for being aware of its place in my life.
I think of it as a dog. A feral, mastiff-type animal with a strong body and an even stronger will. If I don’t keep it in line each day, it will easily overpower me. I medicate it. And I learn how to dominate it, to keep it submissive. 
But it doesn’t like it. 
It longs to take advantage.
Sometimes I get weary of controlling it and it leaps at the opportunity to run rampant. I lose focus. I crave excitement. I act foolishly. The dog grabs me by the scruff of my neck and shakes me until my teeth rattle. 
On some level, I enjoy it. I get a thrill from being between the monster’s jaws, not knowing where it will take me or where I will wind up. 
All too soon, however, the highs end. Reality hits. And I’ve done it again. I’ve hurt those around me, those I care about, those I love dearly. They are dealing with the fallout, wondering if they can ever trust me again, wondering if I even care at all. 
I do care. 
I want to be trusted.
Medication will be adjusted. Therapies tried. The dog will be fitted for a new collar, though it will whine and scratch and struggle to get loose. 
I will never be free of the dog. It is a part of me, and I a part of it, just as my heart and lungs are a part of me. Hopefully, those who love me can see that, and can extend grace for the times that are overwhelming. If not, perhaps they are not the people who need to be in my life at all.
