Major dependency to Gabapentim

So since about October I’ve been abusing gabapentin. it went from taking 2400 mg a day fast forward to now and I’m taking about 9000 mg a day. The guy who I get them off of doesn’t get them anymore and I’m already feeling withdrawal what should I expect because I have a feeling it’s gonna get worse. I know ima fuckin moron. I managed to get off fetty and meth. But gabs got me by the balls.
