The image with the quote that says something on the lines of "When you're in a relationship with someone who is mentally ill, you are in a relationship with a mental illness, not a person."
How would you explain that?
Mental illnesses can affect every part of a person’s life, to the point where they’ve “lost” themselves. They can make you act, behave, think and speak a certain way, that creates an unhealthy state of mind and being. Those who have any sort of relationship with you are affected by how and who you are, in one way or another. If it is predominant enough, a mental illness will take over and at times that is all you can see in a person.
