Just totally frustrated, needed to vent.

It's been almost 1.5 years since I joined this company after college, and I am just starting to realise that things are not going well.

Some context: I was working with a good big client where everything was going well and the seniors were looking out for me and I was building good ground level knowledge and was the go to person for many tasks. Then my manager pulled me into a different project with another client and I'm just not able to establish myself in this team. And now I'm afraid that I won't be considered for promotion.

My peers who joined with me have started to take up the elevated role, they are presenting to clients, leading calls and all. But I'm still grasping nuances about the data and it's so difficult to work with the seniors on this project.

The consultant is worse than Kejriwal. We'll discuss the steps and get proper alignment today, and tomorrow she'll be like when did I agree on this? This is not what I asked?... I even started to use the group chats to tell exactly what I'll be working on so that I can maintain a record that this was discussed, but every time there's a mismatch in her expectations and my work. And now it's just getting too much rework each time.

In this team, I don't have a single person I can talk to about my challenges. I thought I'd talk to the manager, but I don't want to come off as a slob who doesn't want to do the work. And trust me every day, I try to log in with a positive mindset that today I'll proactively communicate everything with her but at the end of the day it's always just me and my frustrations and a ton of rework for the next day. If it goes on like this, I'll never be able to showcase that I'm ready for the next role and eventually won't get the promotion, shile my other peers are on track for it.

Senior consultants on grapevine, any advice on how to make it work? Please, this is a cry for help!
