Doing what you love is certainly beneficial for a happy life. It sounds like you are really limiting your options with the specificity of wanting to only teach college English. don't you need a masters degree to teach at college? I know the community college here requires it. I would put more research into what options you have. if journalism classes don't interest you, what else may be suitable? what can broaden your career options and goals?researching these things can help reduce your stress.....take care.
