If I were to see someone with chronic depression doing nothing with their lives but complaining and feeling sorry for themselves that they can't experience full pleasure in life, I would not frown upon this person at all. I would completely understand what it is like to have chronic depression and that it gives this person every right to sit there, feel sorry for themselves, and complain. I mean, who wouldn't complain and feel sorry for themselves in this situation? Especially if this person is like me who views pleasure as the most important thing and only wishes to no longer have depression and be able to fully enjoy life again. I suspect very few people actually wouldn't complain and feel sorry for themselves in this situation.

What I would say to this person would not be something harsh and inconsiderate of their suffering such as "Stop feeling sorry for yourself and do something with your life." Instead, I would say something like "This attitude you're having is very unhealthy for you. Please see a therapist and try your best to do things in your life because that is likely to make you eventually feel better."

Even simply going up to a person with severe depression and saying "What can you do to make the best of your life despite your depression" is cruel and inconsiderate of their suffering because the depressed person was likely seeking a complete escape from their depression and no longer have it ever again. Therefore, this depressed person was hoping for other people to say something such as that this person will completely get over it and never experience it again. So by stating the quoted message of "What can you do to make the best of your life despite your depression," that denies and restricts this person into a world where they have to deal with their depression and make the best of their life anyway despite of it which would make this type of person feel worse knowing that he/she can not (and perhaps never if the depression is chronic and lifelong) experience full enjoyment in life again.

Therefore, advice to give depressed people such as myself would have to be that of false hopes by telling these people that they will completely get over it and never experience it ever again. Then from there, the person who gave such advice would try to convince the depressed person that this is true somehow (through presenting false convincing pseudo-scientific evidence and such). Or even scientific facts that are true because there are people who have completely gotten over depression. But this person would have to present these scientific facts in such a way that convinces the depressed person that he/she will, in fact, completely get over and never experience depression ever again.
