Having experienced both severe mental and physical pain, I would rather experience neither!
But as a person with mental illness, I know that it’s easy for those who have never experienced the excruciating torture of mental self-flagellation, unremitting obsessive thoughts, distorted thoughts and perceptions, paranoia, suicidal ideations, and such to dismiss our pain and tell us to “get over it.” Or “pull yourself up by your bootstraps.” Or some such empathy-deficient nonsense.
