An adventure

I work at an academic laboratory as a part-time job. There are 15 students at master of science level. Usually I love to help each others on their projects, out of my duty. Unfortunately there are two envious students who try to deception deceive other students!!
These events was started from about 2 months ago. Yesterday I felt no body (should be one word: nobody) liked my presence there! So, I abdicated from (you can use either left or quit here, abdicated isn't usually used unless you're talking about a king/queen/throne) the job while even though its income was so necessitous necessary for me.

Usually I love to help each other (others) on their projects, out of my duty. Unfortunately there are two envious students who try to deception (make it verb) other students!!
