Can someone give me a few pointers on my poem?

Question

I dont think this is good at all.

Pain

How shall I explain my day?

As I dip my toe into the mushy sand of the cold

and warm spots of the lake, I feel for shells that seem to be fake. I grab them with my feet, they cut me like broken glass.

The pain is worse than i gain on that hot summer day.

Answer 1

I like the idea of the poem, but to me mushy describes food like bananas or relates to Valentines day, rather use a word like spongy or grainy. Why do the seashells feel fake? Go into depth about why they feel fake and what makes them this way. Also, find a different simile instead of broken glass, this a an overused phrase. Why is there pain on a hot summer day?
