You're just missing the point entirely. Fry isn't setting up Cancer and Diabetes and Depression or suicidal thoughts as equals, but rather as equally likely ailments. "Make an effort" is blaming the victim for something usually out of their control which is similar to blaming you for getting cancer. Imagine if you were telling someone with skin cancer or lung cancer that they should "make an effort" to stay out of the sun or quit cigarettes. You're trivializing the disease that's already there.

And you're not the only one. This is a common attitude people have. It's as if people who really feel detached from this life and want to end it do not have that right. Instead, millions of people would rather sit down and debate whether it's ethical for someone to kill themselves or have a physician-assisted suicide. Maybe we all want to believe that everything is a Hollywood-esque setting where you just need to find the right people and love of your life to get everything back together. In reality, mental illness (cyclothymia, in this case) is just as real as every other illness and you can't just "make an effort" to get rid of it. I'm sorry about your illness, but try to not to trivialize other's, it isn't a competition.
