i'm not a awesomely pro Zerg user,but i tend to face some frustration, just like u now. if you'd like to,i can help guide you until u r more OP than me though

btw,playing Zerg for an almost-newbie player is quite hard.mostly ppl would go Terran/Protoss,as u get to play them in the campaign.so,i undoubtedly salute u for ur bravery.
