I feel overwhelmed at my job and don’t know what to do

I work in a bank and lately I feel very overwhelmed with my job. Every day I receive more than 40 emails and each one takes time to check and reply. I’m expected to finish them all in the same day. On top of that I also have 3 Excel files that I must complete very carefully.

Most of the work seems to be on me. My manager usually handles simple things, but if I make any small mistake he points it out immediately. When I do something right, he never says anything.

I feel very stressed. Sometimes I can’t even take my break because I’m trying to finish everything. Even on the weekend I keep thinking about Monday and the work waiting for me.

I’ve been in this job for less than a year, so I’m still new. But I’m already handling things that feel bigger than my experience, and even people who have worked here for years didn’t handle some of these tasks.

I’m really tired and it’s starting to affect my mental health. I also feel scared to talk to my manager because I’m worried he might think I’m lazy.

Has anyone been in a similar situation? What would you do?
