So sorry for your loss. I'm sure you will find something here. I found these through 'Good Morning Britain' helplines. These in particular for suicide:
SOBS - Survivors of Bereavement by Suicide
Helpline: 0300 111 5065
www.uk-sobs.org.uk
SOBS exists to meet the needs and break the isolation of those bereaved by the suicide of a close relative or friend, aiming to provide a safe, confidential environment in which bereaved people can share their experiences and feelings, so giving and gaining support from each other.
SOS Silence of Suicide
For support call: 0808 115 1505 (8pm to midnight M-F, 4pm to midnight weekends)
We support everyone affected by suicide, whether they be bereaved, having thoughts of suicide, or have attempted suicide. Everyone is vulnerable, especially right now when the world as we know it has changed, bringing mental health fragilities to those who have never before experienced them and an escalation of poor mental health for vulnerable people who were already struggling.
