How do I go about dropping my classes ...?

So I'll try and make this short ...I registered for full time classes along with planning to work full time this semester too. My work schedule completely changed on me (I thought it was temporary) so I've basically skipped most of my classes. I've had so much crap happen these past few months (both personally and financially) that I need to just go ahead and drop all of my classes (so the failing grades wont go on my GPA).

I'm a determined person and there's no doubt that I'll indeed finish school, just right now needs to be focused on paying the bills... How do I go to my counselor to do this? Wont she just look at my poor attendence and laugh in my face? Will they let me back in next semester? Im so embarrased and ashamed of myself but stuff happened that wasn't in my control. I didn't think my work schedule was going to last this long but it has, and it's going to be this same schedule until December.

I can't even tell you how embarassed I am because I let it go this long ...Im so afraid they wont let me register for classes again because of what happened this semester.
