Help with teenage daughter

HELP!

I am in desperate need of some help and advice

My daughter is 14 and a half
She is diagnosed anxiety, depression, attachment disorder and just recently ADHD.

She does not have a relationship with her father ( we seperated 4 years ago)

She Started Ritalin and have had some amazing results. When she actually takes them.

Having some massive issues at the moment.

She currently has a boyfriend and the relationship is very toxic, verbal abuse, manipulation, control issues.

She is Sneaking out at night or sneaking him in, getting in cars with unlicensed and underage drivers. Skipping school. Disrespectful , rude, the list goes on and on.

I am at my whits end I am exhausted. I have other children in the home and this behaviour is impacting our home in so many ways.

I have removed her privileges (nails, lashes etc ) and taken the SIM card out of her phone.

I am am emotional wreck. I am falling apart. I don’t know what to do or where to go from here

My family is falling apart right infront of my eyes
