well, i'm truly sorry that you are having such difficulties.
instead, if i can offer a suggestion.
set your supplies back to normal. how ever, pick one product type, and try mastering that. for something that you might have 3-4 corps of, and try just that one. construction is a good one. trying setting your construction corps supply to 120, then contracting just concrete to it. and give it a little time to kick in.
most players never get this. its an advanced skill. when i was a newb, they just told us to not use the CM, and they'd leave it at that.
but it looks like the GM are gonna put an end to this, anyway.
