As you may know, I have been working on a specific point of research during one year of my PhD. I am extremely passionate about that topic, because I found problems that can be solved and improvements for the system. For this reason, they did not like me. In particular, one collaborator always underestimated me and later persuaded my ex-PI that my work is doubtful.
Now, I am a research assistant in another distant country. The current PI knows my situation and takes advantage of me. They forced me to work on a topic way off from my background. Moreover, I was shocked to see that they don't have any experience and that there are hostile vibes between senior researchers, which bazzled me, besides the very low payment I receive.
Now, I am trying to apply for other projects, more similar to what I have been working on before. The dilemma is the collaborator is mainly involved in different projects by different research institutes. I have to confess they are the most dominant collaborator, and it is a very small circle. I am literally expelled and a pariah. Even if I tried to find funding for the project, I am afraid they will not approve of my work. I feel in a dead end. I tried to apply for other research topics too, but I failed. I am really passionate and see the potential behind continuing in this research line, it feels like I'm fighting against the Gods of this research line. I am totally hopeless. What I can do in that case?
