I'm the opposite. I'd rather have a physical ailment or injury, because at least it is something that can be seen and treated. Sometimes it can even be cured permanently. Emotional pain and mental illness never really go away. If you're depressed, you're depressed all the time. It may be better on some days than others, but you know it's coming back. Medication doesn't always help, and it can have really bad side effects. If you have a physical illness, people believe you when you say you're sick. If it's a mental illness, they just tell you to snap out of it or get over it, like you can flip a switch and turn it off.
I wish I could take a pill and change who I am.
