You have no idea how bad mine was :y First time I spoke to anyone in english was when floop78 invited me to play DayZ with him, Kowla (i think) and someone else. It was awesome but they didn't understand what I said unless I repeated it multiple times, haha. I think Tyzi was the first one to hear me speak out of the people that are still around. She taught me loads of shit with pronouncing words :)
Right now I'm mostly just struggling with speaking faster.
TL;DR
Do it anyway u fagit, I wouldn't make fun of you and you'll improve as soon as you loosen up.
