Overwhelmed by the replies and very thankful we have this thread. Getting it off my chest has helped me acknowledge the issues I have and I managed to have a quiet night of watching the World Cup.
Regarding work, I think I've just accepted that it is what it is and there will always be other jobs. Need to get myself right before I can consider taking any real action. Based on how they've treated me up until this point I doubt I'd want to be there anyway if various actions were taken. I'm considering resigning as I can make that look better on a resume, and I have fairly good references and contacts from previous bosses. Still weighing up the pros and cons.
I agree that I need to prioritise my headspace, just hard to make that call when a few people are relying on you to hold it together.
Going to book in with my GP today. Been seeing the same one for years so hopefully I'll be given the right avenues to go down and be on the mend before Everton's season begins to add to my fume...
Thank you again.
