Rethinking my career

I went to grad school to be a therapist. I’m 7 months out of grad school working at a psych hospital and I am seriously rethinking my career choice. I hate my job so much. I am so stressed out all the time and I just don’t want to do this anymore. I feel like I have to because I spent so much money on grad school. Has anyone ever gone through this? Have any therapists ever gone through this? I’m just at such a low because my job sucks so much.
