I'm sorry you're struggling Apotheosis I hope your GP is sympathetic and can get you in to talk to someone. I don't know where you live in the UK, but I know in some areas you can self-refer to talking therapies. You could try googling Improving Access to Psychological Therapies (IAPT) where you live.

I can sympathise with you regarding family health issues and lack of MH support as that is my situation currently too. My grandfather also has advanced dementia and my Mum is currently in hospital with liver problems. And the CMHT is being useless since I left hospital in Dec. So I can understand some of what you're going through. I really hope that you can get some support soon
