Getting off paxil CR?

I got prescribed Paxil Cr 1.5 months ago with a dose of 12.5mg. I was on that for about a month, then my doctor uped the dose to 25mg. I took 2 of the 25mg, realized I didn't like it and felt sketched about double dosing, so I cut them in half (which I know you arent suppose to do). I took about 4 of the half 25mgs and then just stopped cause I didn't want to deal with it. Its been 3 days sense I have taken any, however after reading about withdrawals I got scared and took a 25mg which probably wasnt smart. Ive been up all night trying to figure out things. I'd like to quit cold turkey but am scared of these so called withdrawals and the dangers??? Why cant I just stop taking them?? I don't see what the big deal is?
