How have you guys dealt with feeling lost?

I'm sure I'm not the first person in IB feeling this way, and I'm sure I won't be the last. I came into IB bright-eyed and bushy-tailed. Everyone around me, from family to friends dissuaded me. Not because of my personality but they all thought that the biggest draw of IB was money and I had equally high-paying and progressing options coming out of college with a better WLB. This might sound like complete BS, but frankly, I took IB more for personal development. I wanted to polish all my interpersonal skills and build a work ethic that would serve me well wherever I went. And I have given it my all. I've taken every single stupid comment that has come my way, every dig, every dressing down on the chin. I've hardly said no to work, committed everything in my life to making sure I've been available and instilled in myself that, even if for a brief moment, this is all I will do to get the most out of it.

Increasingly, as you all may know, this has become more difficult. I find myself spending more and more time filling out mundane and redundant tasks as I've become more efficient in the "smart" ones. I've realized that my bosses scrutinize pointless shit like folder organization and saving files down much more than the stuff we put on pages. I've realized that my peers hate this job and everyone is just trying to get to Friday only for it to pick back up on Sunday. I feel claustrophobic in the office everytime my email notifications pop or I get a call from someone. I'm not burnt out, tired or depressed. I am unhappy but I wouldn't say I have difficulty getting out of bed. I guess, I just feel like I've hit a wall and I don't know what to do. Was this all that IB was supposed to be? Refreshing comps and sending email bumps to get calls lined up? Being available at 11pm on a Friday just to confirm receipt of a document that should have been uploaded to the data room? 

The worst part is, who can I complain to? My fellow peers hate this job as much as I do and ranting to them is literally just ranting to them. Even the associates above me are either ones who just nod in agreeance that this job sucks or are lifers that will definitely ding me for my work ethic if I complain. My staffer is a nice guy but man showing any sign of being tired or frustrated is the easiest way to appear "weak", a concept I have never gotten. No one can help me except for myself and I know that.

But I still feel caged. All the places that are recruiting are the same experiences packaged in different wrapping paper. The places I chose not to go had dedicated undergrad recruiting pipelines and it just seems like a super difficult path to pursue now. There are also good people in this job, people who have vouched for me to be here. People who continue to look out for me and want me to do good as they see me for one of the top performers of the group. The voice in my head keeps saying, "don't bail before the end of 2 years - give it your all and see what happens after". But for what? For resenting the cubicle I have to spend 90% of my waking time in? Even reading this I keep telling myself -- just leave. Go do what you enjoy. But what about the IB - PE - Grad School - xyz path that I'm on and very easily can stay on to something 0.0x% of the population dreams about having. Am I that ungrateful that I'm willing to throw that away now that I have it in my palm?

I'm not even sure what I'm looking for in this thread... maybe some sort of comfort, optimism, experiences or maybe a reality check that it doesn't get better. Maybe I'm looking for an exit but it feels like I'm in the fast lane on a highway and just keep driving past those.
