This is a subject I have very little knowledge on and will not pretend to have any personal experience on the subject. A team who do have experience are Help Musicians UK. They will offer advice to musicians, managers, tour crews and record labels. If you work in the music industry they are there to help. After the death of Chester Bennington the service was created as part of their Music Minds Matter campaign.
Don't be afraid to reach out to the helpline 7 days a week by calling free of charge on 0808 8028008. You can also email at MMM@helpmusicians.org.uk
