Am I stupid or they just dont like me?

don't worry. you'll get the hang of it. most of the new people at my work take months. and if you're sick and can't find some one just call in. don't abuse that though. if you are dying i can ure you you will not have to go to work. if you faint, your coworkers will make sure you're ok. most people can't stand it when they start but they adapt.
