Olanzapine/Xyprea being pushed take it?

My symptoms git lot worse the last 8 weeks, the anxiety intrusive thoughts off the scale. Had call with psych they are pushing me to take this, but it sounds horrendous drug, she was so condescending treating me like I was psychotic. Sounds awful to come off. I did try get some diazapam for just short while, but she’s very anti. Seems the AP can cause diabetes, pretended I had taken it for few days, but she’s insisting try longer. I have bad anxiety not psychosis., tried seroquel fir few days that made me feel awful. Any advice please.
