I would really like to lend you a hand but I sucked at using zerg. Let me know if you like to practice against terran though. I might be able to show you some counters to some popular terran openings / strategies at the level you're playing at.

Btw I really like your opening post. It shows your passion towards the game and willingness to learn this game. Much better than those one liner "please teach me how to win".

Some tips: you're having a SEA account right? You can have access to north american server. There are tonnes more people who play custom games there, whether it's 1v1, 2v2, 3v3, 4v4 or even FFA. The latency is higher but shouldn't be too huge a problem.
