Well there are many different places you can go to for help.
If you are working with CAMHS it would be really good if you contacted your main worker in the office they are located. Now I know it can be hard to make contact as it seems everyone is busy but if you can’t contact them them ask to speak to the duty worker.
If you are immediately worried about the safety of either yourself or a child then call the police on 999.
