I have been teaching a humanities course at a higher education institution for about more than three years now. I am expected to get full tenure this year. Perhaps it is the only chair dedicated to my field in my country; it is certainly the only one in the subfield I teach. In other words, yes, I am the only professor who teaches that subject in the whole country, and the only professor totally dedicated to teaching and researching in the broader field of study. However, before I took the position, I was not specialized in the subfield I teach now. At the moment, my research and publications in field A are split between subfields A1 (in which I pursued research for my MA and PhD) and A2 (my new teaching position). To complicate things, I am in a multidisciplinary department in another field.
There is no available teaching position in my whole field (A) in the whole country in the foreseeable future (say, 10-15 years, unless a miracle happens). I could teach in related fields, and that is what I am doing (and plan to do in better conditions in the not-so-distant future).
The conditions under which I work might be described as both appalling and depressive. I know there are worse conditions in my country; and I know that I earn just as much as anyone else, but that is not the issue. The issue is having no perspective of future research; virtually no intellectual life; almost no contact with other faculty. There is only one room for more than 18 professors in the department; in it there are some 5 computers, 3 of which do not function. The library does not have the books I need for my basic, mandatory course -- in fact, it only has one textbook I use in class! I have to make do with articles and books from the Internet, when and if available. Grants and funding are virtually non-existent. I am in debt because of a conference in which a paper of mine was accepted. After that, I could not attend 3 international conferences because there was no funding.
So, in the end, my question is this: is there any way (attitudes, habits) to make academic life more bearable under these circumstances? Should I give up research and focus on teaching basic subjects, at the risk of fading into oblivion for not publishing?
A note: I cannot just "run away", because, as I said before, there is no way I can find a similar job anywhere. I have been trying to busy my mind with other part-time activities, so as not to worry or stress too much, but that also leaves the feeling that my "real" job is useless, or worse: a fake.
