I have recently discovered something about my self that I never really noticed before. The past 4 days I have been really busy with life and school and never really had time to practice my upright. For those four days I have notice that I have been getting my depression symptom come up without the normal triggers. So I had my lesson today with my teacher and almost instantly when I picked up my upright to go walk over to his office I felt all my depression symptoms go away. So I have come to the conclusion that when I don't practice or play my upright I get depressed. This definitely encourages me to practice more if I didn't enough already but anyone have similar situation.
