PTSD FROM MY JOB

So I work NOC shift I e been doing it for almost 2 years and I enjoyed working 24 hours a week but then they needed more help so now I work 32 hours I’ve been noticing that it’s draining me and I have a 4 year old daughter whose in school Monday-Thursday all day. I haven’t been able to spend much time with her and feeling depressed for months. Then one of my residents attempted suicide on my shift I found him covered in blood and the experience was traumatizing. I later found out he did not survive. I took a few days off and I’ve been back since it happened and it’s just not the same it’s so hard for me to bring myself to that place I’m overwhelmed with emotion and anxiety and stress. I have PTSD symptoms still and it’s been a couple weeks....I truly want to let go of this job but I don’t have anything lined up but I’m not even worried about it I’m more concerned with my mental health and being ok for my daughter. Any advice? I’m supposed to work tonight but I don’t think I can do it...
