When working becomes painfull to do but still one must..

I have been working with my client for more than a year now. She had been great even though she has dementia. My co workers are what bothers me. Two does not talk to one another because of a petty issue and pride. I do not like it. Atmosphere feels like it is suffocating me everytime. Then i feel like one is taking advantage on things manipulating to benefit only their wants. I cannot do anything and i am beginning to feel like i cannot endure it no more. I cannot tolerate environment that has a negative vibe. It is not that i am avoiding it. I am just the type that cannot take on things that makes me feel negative. I will hang on since i need it. But just for somw more time. I love to work. But i do not like working when i do not feel positive. I handle people. They are my work. I do not want them to be affected. Just a little bit more. Take the Nclex test. That is the goal. 😏😏
