Genuinely the most isolated and stressed out I've felt on a shift (coworker)

Today we got through a staff meeting where the pseudo manager decided, rather than give me constructive criticism directly, they wanted to air their laundry and have our resident coordinator talk to me and a new staff at the home.

Afterward pseudo manager just straight up ignores me, tells the other staff to call him if needed, and goes barely looking at me.

Shift goes along but all clients are hanging around the new (female staff). I start making dinner but wall away, and she just starts making it without asking me at all, washes, puts stuff in the drying rack.

2 clients decide to go out with her. They come back, apparently one decided to try and grope her, she's cold to them rest of shift.

She sits in the office, eats, and has a private conversation with another client. The client clammed up when I approached. I asked this client twice if they were okay and if anything was bothering them, and the looks they give me are suspicous and untrusting. They're more relaxed around the other staff member. This is not the first time this has happened either.

I received a disciplinary call earlier today because a client claimed I am sitting in the office with the door closed listening to music. I do close the door but that is to answer phone calls.

She gets a phone call from another group home from someone who is a higher up, talks to them, hangs up and walks back put of the office. The person on the other end has been indifferent to me since day 1.

Sits with 2 of the clients and is suddenly more talkative than when I sat in the office trying to talk to her; she wasn't engaged, played on her phone, talking to her was pulling teeth.

The client that tried to grope her decided to wait and not brush their teeth. This is a common behavior. She almost gets into it with him and I defuse by asking him to come down later, which is no problem and not over "medication" time.

I've put up with a lot of bullshit but this is the first time I feel spiritually wounded by how dismissive/noncommunicative the job is. I genuinely feel like they want me to walk, or just don't care if I do.

I got in touch with a different coworker who warned me that this new/substitite staff is known to start trouble and that I should keep my mouth shut around them.
