Safety
Some of this needs a person, not a website.
This page is short on purpose. If you recognise yourself on it, stop reading and act on it.
Now
If you are thinking about harming yourself, or feel unable to go on, contact your local emergency services or a crisis line immediately.
Chest pain, breathing difficulty, collapse or a sudden unexplained physical change: emergency services.
This site does not list telephone numbers, because they differ by country. Your local emergency number works everywhere you are.
Money
If money has become the emergency, no money for food, losing your home, utilities being cut off, that needs a free debt or advice service now.
Pensions, packages, investments and tax are for a qualified, regulated adviser. Be wary of anyone who approaches you with an opportunity soon after you leave work.
A doctor, not a website
Low mood that has gone on for weeks. Not leaving the house, or not seeing anyone. Drinking more than you were, or drinking to get through the day. Sleep that has gone. Get it looked at properly by your own doctor.
