It takes tremendous strength for any of us with a mental illness to function in this world.
Panic attacks, depression, mania, hallucinations, psychoses, obsessive thoughts, compulsions, and myriad other states of being are symptoms of a disease of the brain.
We don’t call people who are physically ill “weak” when they have tumors, heart attacks, cancer, diabetes, and so forth.
If you have a mental illness and are functioning, you are a badass. And even if you are functioning on a very limited basis, you are not “weak.”
