Howdy!

Was wondering if this is a prominent issue with others and how i could maybe try and find inspiration from other things or what subjects would be less depressing to write about and how i would start writing less sad stuff. 

Depressing things are beautiful
You needn't search for an alternative source of inspiration
Suck it up t'ill it's dry

Aside that, try reading all kinds of poetry. There is art in the subtleties, and you will come to appreciate language as a whole. Poetry is more than the words, and all about them at the same time.
