Looking for some rejection letters

Slightly over two years ago I finished my first creative writing class.  I really wanted to take it earlier than that -- like in my first or second year of university, but the prospect of submitting work to try to get into the class intimidated me.  Also, the idea of workshopping my own stories if I got into the class scared me.  Anyway, I have loved every creative writing class, and at the end I have always wanted to submit some of my work to literary magazines or something.  In the first and second classes I took we never focused on publishing, but last semester in 485 poetry (or whatever the title was) we did.  We actually had an assignment to study some literary magazines and choose one that we would send our work to.  I did the assignment, and I really wanted to send my work off.  By the end of the semester I even felt like I might be able to get some of my poems published.  Sometime in the summer I even emailed Medrie and asked her about what to put in a cover letter, and she graciously sent me an old one of hers to help me out.  Then all summer I got busy with social events, and new writing, and family obligations.  When I was alone at my cabin I would think I really need to get my own cover letter done.  They're not long at all and I imagine take only like ten minutes.  Still, now its December and I haven't finished, or started it.  I am not even worried that my work would be rejected.  That would be fine.  At this point it would feel good just to know that someone in charge of reading poetry or short stories for a literary magazine read my work.  Anyway, I feel like I am letting myself down (and my creative writing professors) by not even trying to get any of this work published.  So, I am promising myself (and the versions of them that are in my head) that this Christmas break I will finish cover letters for my poetry and one or two short stories, and I will send them out.  Any advice from anyone on good ways to do this, or good places to send work would be awesome.
