ugh i could absolutely write essays about the fact that tim drake is probably the most depressing out of all the batkids. His birth parents hardly cared about him (he is book definition of neglected) and we see that he didn't have that many friends in school. And then he was pressured into becoming Robin and suddenly that's where he felt needed. While reading all the comics i really noticed how Tim is ignored by Bruce unless he is Robin. The only times we really see Bruce care about Tim is when he's injured. Hence, neglected.
Of course Tim isn't going to point this out because this is how he was treated his whole life. But he subconsciously knows that he is only needed while wearing the Robin suit so that's what he relies on. That's why I think he reacted so negatively to Dick replacing him with Damian as Robin. That's why I think he never switched to wearing the bat like everyone else did and instead changed to "Red Robin."
Tim Drake isn't his own person outside of being Robin, and nobody in the series is helping him change that.
