In the US you usually go to the ER and they help you get to wherever you need to go or they hold you and offer care from the hospital psychologist etc. (call an ambulance or get a ride if you need too)
U could start off with your health visitor, they'll point u in the right direction for your area ❤️
I’m in the us I went to the er. They gave me 2 options-4 days in inpatient or 2 weeks in outpatient
