Co-worker Suck

hey, guys just venting, i have been in dialysis for 3 years started as a tech I'm currently a lvn, and just got accepted into the bsn program:yeah:. I am have a very hard time with my co-workers:no:. I am very strong mind. I let people no how I feel, but I am cautious, and I do not think that sits well with most people . My co-worker I don't know I feel like they have a target on my back . There is something else they do not judge on work performance or how you treat the pt. they judge on how you Shi***** I dont know what they judge on. I try no to care but there is always something going on people complaining and it is soooooooo draining. What do I do? How do I stick with it? Dialysis has allowed me to continue my education and I am not quite finish yet, but I am tired of all the fighting and back stabbing. I just want to work in peace. Is this just at my location? My boss is a lune.
