Situations bring me to a place in which i can't express myself and When i reach that point I have a brief (quiet and alone) meltdown. It happens way too often to be the blues.
Little tiny things do it too. My mom asked me to play her a full song all the way through (i've been playing for years, yet she claims she's never heard a full song) and i just couldn't. For whatever reason I couldn't. She suggested i stop receiving lessons. It just made me feel like all of a sudden my hobby has requirements, and how much that twists me up. I try to explain this but an argument insues every single time. I go back to my room and meltdown after trying to say what's on my mind for 30 minutes.
Then when i see pictures of myself smiling, i don't recognize the person as me.
It's like i'm suffocating without a bag on my head. That's what it feels like.
Every one has moments where they just simply can't express themselves. As to your music, you shouldn't feel that your form of expression has limits or rules. If music limis you in ways you don't like, find another form of self-expression. Try writing, acting, painting, sculpting-anything that relaxes you and channels your feelings in constructive ways.
It's not that the music has limits, its that it has requirements placed upon it. I act too.
I just wish I could channel my feelings into my life instead of my art.
