Minna,
Frustrating as it may be, your teacher is mostly right. Vibrato is very difficult to teach because of all the tiny physical things that need to happen. Some people get it quickly, some people don't.
My best advice is to not force it, and remember that a good vibrato is not caused by tension in the arm, but by having an exceptionally relaxed arm. The movement should originate in the shoulder and upper arm, not the wrist and fingers.
I don't like giving technical advice over the internet, as I don't know exactly what is happening to you when you try to vibrate. With this disclaimer, here is how I would practice vibrato: 1. Make sure you understand the concept of the motion you want to make
1.a. Vibrato obscures the pitch of a note very slightly, it is very important that you only vibrate up to the note, at no point of the vibrato motion should you play sharper than the note you are playing. I.e. if you are vibrating a D your vibrato should take you from a perfect D to a slightly flat D to a perfect D to a slightly flat D, etc.
1.b. Realize that you do not need to press on the string with your left hand at all. You will get a good sound by pushing the string only 90% of the way down to the fingerboard. Do not squeeze. You could try playing without your thumb on the neck, this will let up some pressure.
2. Practice slowly, without a bow. Focus on one thing at a time. Put your left hand lightly on the fingerboard and slowly start making the correct motion, speed up as you are comfortable with it. Once you've done this for a few days or until you are comfortable add in your bow.
3. Realize that your right and left hands are not connected when you play. Playing loudly is about the bow. Don't squeeze your left hand, this will make vibrato exceptionally difficult.
4. If you ever feel that you are tight, or are shaking the cello when you try to vibrate, stop. Take a break, analyze what is wrong.
5. Accept the fact that this take a long time to get a really good, consistent vibrato.
