Dear Desperately sad Mum
Hello and welcome to the forum. I am so pleased you found us. Hopefully we can offer you support and suggestions.
I can understand this is very troubling for you and makes you scared to call an ambulance in case the scenario plays out as it did last time. Paramedics are not trained to handle people who become violent for whatever reason. They do cope with many different events and can often defuse a situation. It really depends on the what's happening at the time. Not being there I cannot say if the police handled the situation with more force than necessary. It may well have been to stop your daughter harming herself as well as others. It all sounds very disturbing and I can see why you are reluctant to repeat it.
On the other hand your daughter does need help and I think you agree she needs to go to hospital. Did the paramedics call the police before they arrived or when they arrived and realised how difficult the situation was becoming. I ask because you may be able to help your daughter to be a little more calm and not need so much restraint. I also understand your daughter may be beyond reasonable at this stage and restraint is the only option.
I'm sorry I cannot offer much in the way of helpful suggestions as this is not something I am familiar with. My main concern is for you Sad Mum. I can hear how distressed you are at the possibility of the same scenario playing out again. I can understand if it was my daughter how desperately upset I would be and the thought of going through the process again is horrific. I am sure you know how much your daughter needs help. When you call the ambulance can you ask them not to call the police immediately? Can you go in the ambulance with her to the hospital? Would this help to calm her at least until the paramedics can give her some sedation.
I am sorry I cannot offer any other practical suggestions and I am worried about you and your daughter. The good relationship between you and your daughter is important to you which makes it even harder to be the cause, as she will see it, of putting her through this.
We are hear to listen to you and chat. I hope all goes well this time.
