I'm in a total disaster right now because it feels like I have no chance of being a researcher anymore. Months ago, I submitted my Bachelor's thesis. Days later, I realized that I printed a wrong version of it (the version before the final) so I asked permission from my adviser and the librarian if I can replace the copies because of the mistake. They allowed me.
Weeks later, I realized that there was a term in my abstract that might need to be cited. But for the record, I cited this term in the body of my research. I consulted my adviser whether or not I violated something with that. She said that it was okay because I already cited it in the body of my research. However, I insisted and ask if I can add a citation just to be sure. She said okay. So I had to replace my copies of thesis again.
Lately, it occurred to me again that there was something wrong again. I think that I failed to cite a secondary source in the 'limitations' part of my thesis. Although I already have cited this secondary source as a secondary source 2 sentences before the sentence in question, I still feel that it was not sufficient because we had another similar quotation from an author in the sentence in question. I don't remember exactly why I failed to cite the secondary source in that sentence again. But as far as I can remember, I accessed the primary source. Maybe that is why I did not cite the secondary source.
But it still bothers me because even if that's the case, it might still look like I copied that part of my thesis (although not verbatim, but it totally bothers me still). That's the only problematic part of the whole research. I would like to correct this and give a more sufficient citation for the secondary source, but as I have mentioned, I already corrected my copies twice and they might not allow me anymore. I am so devastated right now, I am afraid that this might bar me from doing research again. Or worst, they might take away my degree which I really worked hard for.
How do you think will my adviser react to this? The last time I amended my thesis, I said that it will be the last time. But this mistake is unbearable and I can't live a day without thinking about it. What if the other faculty members will know? What will be their reaction? I have a perception that academicians are perfectionists and might persecute mistakes like this even when done unintentionally. I don't know what to do, I really don't know what to do.
