How am I bad in English?

I have been learning English as 2ND language sine 2008 but I am not good at it, I was so optimistic at the first however it's unbelievable I am not full skill in it, I am so disappointed now I do not know what to do, I just put my self under this Question What am I doing ? I start to memorize 1100 vocabs it would help me but In Iran there is now any native person to speak , so I can not to speak with any native person, for listening I just watch RT and France 24 ,God TV, VOA. visiting in Iran is not so hard but I do not know why our visitor are low ,I mean we do not have enough visitor!!! but we have beautiful country I love Iran, I am sure you would loved too,
I think I should change fast , and I also should find answer for my question!!
anyway I loved English but it takes much time to learn , if you are learning English now that we can make good relationship together so connect to me, it would help me, I would bring my self-confidence back, thanks for all
