Do PROFESSORS notice when their students are SUFFERING from lack of sleep.. etc?

I understand you're busy but I'm going to be really blunt. DON'T tell your professor that you're ridiculously busy. He will likely take that as an "excuse" for bad grades or something, and suspect that you're hinting that he take that into consideration when giving final grades. He is teaching the class at the level it's meant to be taught at, and you will get the grade you deserve. If you're already getting help from therapy, why do you have this desire for your professor to know that you're stressed? You're already getting the help you need.

I'm confused why a college student with an obvious heavy workload and medical issues is working two jobs on top of everything. You're setting yourself up for failure! I don't know ANYONE who is crazy enough to work two jobs, be a full time student, and take care of medical issues (your stomach). Don't complain to your professor, he/she probably won't feel any sympathy for you. Sorry to be blunt, just being honest! Ok.. I just read your additional details. I understand where you're coming from, not personally, but I have a few friends who are financially independent of their parents and pay for their own education. I get that you have to do what you have to do but here's my suggestion: go to a community college for two years. It's so much cheaper and you can get credits out of the way. Then transfer back to a four year university and finish up your last year or two there. To answer your original question: I still don't think you should break down to your professor. Of course professors have feelings (they are human too) but he/she won't give you the sympathy or empathy you need (that you should be getting from a therapist...) There is no harm in going to see your professor... ask him/her for help, clear up any questions you may have about the upcoming test, and then leave. Good luck in your studies

Not all professors notice. And the ones that notice don't have any way of knowing whether you're cracking under the strain of too much responsibility or just partying too hard, especially if you claim that everything's fine when they make the effort to reach out. So if you're really struggling, then you need to get over the embarrassment and tell them. Don't make excuses, don't ask for special considerations without making it clear that you're not counting on them, but let them know that you want them to be aware of the situation and that you really do want to do well in spite of everything that's going on. That they'll appreciate.
