So hard to become musician

I don't understand as a violinist student(intermediate level). Learning music is form of relaxation. Music can making friends.

But the problem to me why my violin professor see me lots of mistakes in our lesson and I don't understand why. For me it feels me uncomfortable and I am so tired being music student.

So many criticism, did not see your efforts and sensitivity.

I told my professor before that I do have mental health problem but I feel he ignored. I guess my depression getting trigger again.

I am so tired correcting me and every our lesson always sees me, wrong, wrong, wrong. Bad, bad, bad.

The words what the most hurtful to me he said I am slow learner.

I feel so burden not.
