Painting My Feelings Away

I recently started painting as a way to cope with some personal struggles. I thought it would be therapeutic and help me express my feelings on the canvas, but so far, all my paintings seem to have this eerie emptiness about them. I see everyone else's colorful pieces at art nights and feel like a fraud for not being able to match their vibrancy. It's silly because I'm doing something that's supposed to make me happy, yet every time I try, I end up feeling even more alone and lost.
