Treating depression in the Bodensee region

Dear all;

My boyfriend is with depression signs and we are looking for medical assistance in the area of Radolfzell/Konstanz.
Here are our main doubts:
- A psychologist or a psychiatrist? He is pretty depressed but we are still not sure if he needs to take medication.
- Any recommendations about good doctors (and English speaking) in this field and in this area?
- Do health insurances cover this kind of costs? I know that there are usually restrictions on psychotherapy (limited number of sessions), but from what I understood normal appointments with a psychologist/psychiatrist would be covered. Any clue? We still need to make an health insurance.

Thanks in advance!

The first step should be a visit to your regular Hausarzt (GP).
