I agree, but there are also those who have had their lives shattered by suicide of close ones too, and it's important to remember that suicide affects those left behind, so in this I think anger is a justified part of the conversation and I'll elaborate again to try and show why...
Someone very close to me, not the person above, someone way closer, is suffering from both cancer and depression right now, literally day to day, right in front of me.
Love and support has been important, but anger against the depression has had a positive effect, after months and months of being tight lipped and understanding. It's a truly important emotion to wield alongside the others. Unfortunately, we have very little to wield against cancer in the same sense.
Neither of these illness should be being compared here at all, neither is greater than the other because they are not apples and oranges, they are apples and elephants. They are in different wheelhouses and cancer brings with it it's own anger, one that can be brought into the fight, but, and I'm sorry if this sounds offensive I don't mean it to be, but having had both depression and serious health problems, if I had to choose I would choose having depression because it's treatable and beatable and the pain is escapable. I think it's just as important to acknowledge that as it is to have empathy.
Again,this is not meant to belittle depression at all, quite the opposite, it should be a priority to make a point of constantly reiterating that depression as beatable, every time it rears it's ugly, shitty little head. The weakness comes from not being completely open about all feelings around it, negative or positive. Sometimes the eggshells need swept away too.
What I'm trying to say is, empathy or not, anger is a valid and important reaction to suicide as well as every other one.
