I just need to vent

I am 23 weeks pregnant , I work with people who have disabilities, I have always enjoyed this type of work , I quit my job 3 months ago and just came back a week or so ago, they put me in a really difficult home , one client has MARSA , 3 have really bad behaviors so bad they like to hit you , I just do not feel comfortable for once in this field , like I used to . My little babe means absolutely so much to me tbis is my rainbow baby , I also have 2 other Children at home , i only work weekends , that’s what works for me and my family. But I am so dang scared about getting marsa or getting hit and losing my baby , I’m not sure what to do . There is another house in my town where they have open shifts but the HR guy litterally tells me I can’t go there . It hurts because it’s the home I used to work In and I know I wouldn’t have the feelings I do now . I am honestly at a loss I truly need a job until the baby comes but after this weekend I’m at my end with it . Even the staff In the home has bad energy , negative Nancies to the core . Why be in a house where it’s just gonna stress me out .. I plan to call HR tomorrow but I don’t see it going well
