Here are four KIZ, which stands for Krisen-interventions-zentrum (crisis intervention centre), in Winterthur, Zurich, Bern and St Gallen.

In general, such a centre has a 24-hour telephone line. You may or may not reach someone who speaks English; if not, do not be deterred, just call back a few hours later (when the shift has changed) or call one of the others centres.

These are really low-threshold open-door psychiatric clinics, and naturally, each centre has its own concept. In general, a referral by a doctor is not necessary. People in need (whether psychological or any other kind of crisis) are helped on the phone, or by going there for an appointment, or perhaps to stay for a few days (max. 4 or max 7 days, usually). The costs are covered by the general (= basic) medical insurance.

The purpose is to get a break from one’s current circumstances, to be in a safe place, and to have the time to figure out what is happening, and what the next steps need to be.

Even if you live somewhere else, you could call there, and ask them to help you find help.

The “Helping Hand” telephone service is another well-established 24-hour offer. The people who answer are often volunteers, lay-people with a little training by psychologists or psychiatrists, and good listeners. There, too, you may or may not find someone who speaks English, so you might just try again a few hours or days later.
The number is 143. No dialing code, no prefix, just 143.

You might have a look at your medical insurance papers, too, and your insurance card. Some medical insurance companies also offer a 24-hour helpline, in which professionals help one to decide what to do next.
