My father has been getting investigated by police for a while now due to my mental health, section 136, messages I’ve sent?

& his abuse towards me & other members of my family. I was put on a section 136 the other night, got sent home with no support despite this which will be extremely triggering & hard on my whole family. I will become very unsafe & unwell during this process. What am I meant to do? I won’t be getting any support from mental health services during this time other than my usual once a week appointment with a care co ordinator.
