Interesting piece. I felt like this recently myself. Full of emotion and anger. Job well done on this.

A wonderful way to get your anger and sadness out - poetry. You go, girl! Turn that negativity into a work of art on paper (or computer). You deserve better. Anyway, very good. The descriptions made it realistic, especially the cat part (it added a little more so that it seemed normal, not just cliché).

This portrays your emotions quite vividly. Everyone's probably felt like this sometime in their life. Just be careful not to use too many cliches in your writing else it turns into every other loneliness poem.
