Sorry to hear what you’re going thru & glad to hear it’s doing its job though.
Not for everyone but you can email the samaritans if you don’t want to talk on the phone, I’ve found it useful when I’ve needed to unload they’re very good & respond within 24 hours, useful for those of us who are crap at talking. Jo@samaritans.org is who you write to.
Saw this too might be a starting point:
