Lost purple iPod Nano 7th Generation last seen around Levenshulme, Manchester, UK.

I can't find my purple iPod Nano 7th Generation and I am scared I may have lost it. If anyone has seen it please let me know. I got it when I was 13 from my grandma so it has sentimental value, and I use it very often. I don't know where I last saw it. I often go on the 192 bus and am generally around the levenshulme area/ centre of town/ stockport.
