To quit or not to quit?

I'm starting to entertain the thought of quitting school. I don't really see myself going anywhere. At best I can only get like a GPA of 2.5-3.0 for this semester and that is really AT FREAKING BEST. I think getting 2.0 I can tou siao already. With the sucky GPA I had for the 1st 3 semesters, I'm pretty much screwed. I probably cannot enter any local university even if I get GPA 4.0 for all the remaining semesters except for SIM which is -.-

Right now it looks as if the only way out is to complete my diploma and that's it but is a diploma with mediocre results on it desirable? I don't know. I have like zero interest on the modules I'm taking.

I really don't wanna disappoint my parents again especially my Mum. She's gonna pray for me during the exams but I really think that she should just save the effort. I don't deserve it.

I'm starting to sound like Shaq, quitting on teams whenever things start to look bad. Heck I even remembered trying to quit on my ITP attachment at ****** during the 1st few weeks. Am I a quitter or am I just disillusioned? Damn. I probably won't quit school because I don't wanna regret making stupid decisions but failing another module (or more) again will really make me )#*(#%*(#% and it's a total waste of time and effort too.

Anybody out there can give me some good advice? I need all the advice I can get man.
