Hi guys,
You are going through such trying times, and it is important to reach out for support for yourself when you are not sure how to carry on.
You could call the Samaritans on 116 123, and you can also find support for families affected by drug and alcohol use in your area through the Adfam Service Finder Map (https://adfam.org.uk/home).
I hope that this is useful, and that you find the support you need, and deserve.
Best wishes,
Clara
