I am not a big fan of cliches either. They are reductive at best and damaging at worst.

one thing I have learned that depression is definitely not one size fits all.

I am sorry it is so rough for you. I can empathize with the feeling of holding on as being a minute by minute thing.

One of the biggest helps for me came out of a book I was reading a while back. "Just Shoot The Damn Dog" it is a memoir of depression one person's experience with depression. But in it she says that suicidal feelings are not an aberration but rather just a another symptom of depression.

But as I said that is just me. Hope it helps
