Jes, i'm so sorry, this sounds horrible. how old is your daughter and what sort of issues does she have? (just wondering if there are teenage hormones and stuff going on - as well as something else?)
Tell us a bit more about you - what do you like doing? How are you doing today? You have the strength inside you to get through this, so would be lovely to hear what else is important to you.
You're not alone,not sure if you've heard of Young Minds, there is a section for parents that might be helpful https://youngminds.org.uk/find-help/for-parents/
Sending love and hugs xxx
