Living in sint niklaas want to make friends

Well, unfortunately these things take time.  Your speaking should become better and better over time especially since you are working and going to school.  Moreover, if you are working then your Dutch must be adequate.

Are you completely alone here? 

You sound young and it seems the younger people who come here expect everything to happen quickly when in reality these things take time.  In my country living there a year without finding American friends or friends period is unheard of, but this is another culture.  The Flemish are pretty slow to open up and befriend you, so you will have to be patient.  That's what my experience here has been.  Most importantly, you will have to be patient with yourself mastering the language and that does take time for sure.  It is possible; it is nothing that can't be done.

Sounds more like a confidence issue vs. a true language barrier.  You should join a club even if you feel your speaking is not very good.  Practicing in real situations is the best way to master a language.  Of course you will make mistakes, but over time you will get more and more comfortable and confident with your speaking.  Sign up for one of those classes............what do you have to lose?  You might even find a friend there.

Volunteering is also an option.
