Good luck with it all, don't give up.
Sky has some nice advice so try and utilise it
I was copper (bronze) when I first started :P I was having trouble with zerg; unable to inject.. micro.. macro ahhh all so confusing.. too much so soon.
My friends said the same thing as SkyBreaker and that is to just focus on one thing until you've 'perfected' (loosely used hehe) it to the best you can, then move onto something else. For a few weeks I was told to not even watch the fights, just a-move and go back to base building. I thought it to be stupid but it worked nice enough :O
