So what will therapy do for me?

I’m in the military (I work in a hospital). I absolutely hate my job currently because of the department I work in. I just had a miscarriage with a D&C that they messed up. I’m so stressed, overwhelmed, sad, depressed, and feel like I have no will to live. All I do is work my ass off then go home and sleep.

They gave me two weeks off and I just am so sad all the time. Work suggested I go to therapy but I’m scared. What will it help me with? I will still be slaving away in the place I work at and idk how it’s supposed to help me. I’m also scared. I keep backing out of making an appointment.
