Song (?) by J. S. Bach

I'd like to share with you this video from my personal archive. I don't know how many years ago it was recorded... Then I was a student of violin in musical school. I don't remember in which grade I was then. And I don't remember what was exact name of that piece. It is possible to hear in this recording that it as a Song by J. S. Bach.
When I was a student, I had one big problem... It was a performance anxiety. I learned a piece quite well in quite good intonation, but during a concert I was so afraid That sometimes it looked like my hands are not mine. And sometimes I got lost in piece.
I hope you will like this video :)
