Seneca, the stoic philosopher is "somewhat" with the idea of suicide, although I disagree with him... and he suffered from serious illness too. Epictetus was disabled and a slave... but they encouraged living a "good" life, for everybody, a life without additional unnecessary suffering

and what you said in the first paragraph is not how they put it... and I couldn't do their philosophy justice by my wording, especially here... They do!

As you read those opinions, it would benefit you to check out stoic literature extensively, and yes, even from the Roman emperor... It's not only me who says so, but many people from all sorts... including the disabled/chronically ill throughout history...

It's something good for you, if you want it!
