Frankly, I don't know what the "ringing" and "letting go" bits are all about. You don't bother me, my ears aren't ringing, and I'm not holding on to anything, literally or figuratively.Why do I bother you so much? Who's ears are ringing?
Just let it go.
You used to know C, you know Matlab, have a grasp of programming in general and you don't have a due date, so you have plenty of time to go through some online tutorials. I might have offered my services if I lived nearby (I like tutoring/teaching -- that's why most of us are on this board, for free), but I don't. Honestly, if you want live tutoring, you would probably be better off posting something at your school, and asking around the CS department. I would bet very few of us "regulars" or any of us that are qualified, live close enough to even consider this. Maybe you can get a professor there to help you during their office hours (are you in a master's/PhD program? they are usually much friendlier to grad students), or they might recommend a good student or teaching/lab assistant to help you out, or at least direct you where to get good live tutoring.
