shld I quit?

actually I have been thinking whether I shld quit my current job..everytime my colllegues say something abt me, I will feel hurt even if they are joking.. like for example, today, one of my collegues commented that I am not steady because I was answering the karoke calls but I nv check the tickets and all the batam view reservation he have to do himself when actually is my job.. Maybe I really slow in doing anything bah.. the job is giving me alot of unhappiness bah, with my collegues commenting on me even though how hard i tried.. I dont know whether i shld continue this job or not
