Once you start to feel better, thoughts like the one above will disappear and will even seem crazy in retrospect.

It's like....Imagine that you are eating a bowl of your favorite ice cream and you think:

"It is meaningless for me to eat this ice cream. No one would even notice if I'm eating this ice cream or not. What's the point?"

Would this thought occur to you? No, it wouldn't, because eating the ice cream is good enough by itself. You don't need anyone's approval or notice to enjoy your ice cream. Once you start to get better, just the feeling of being alive can be like ice cream is to you now. So good, that it doesn't need any approval or justification or anything more than what it is.
