You've got a lot more problems than this announcement, OP.
It may be that these changes will force you to correct something that has needed fixing for a while.

But whatever im used to the abuse .
And I see a guy who's got a great idea that needs some tweaking.
You sound like this has got out of control on you. You're stressed out, you're tearing your hair out and you don't know what's wrong.
2 suggestions;
1. RAISE YOUR PRICES 10%. You'll exchange some of your volume for profits and you'll slow things down a bit, but you'll make more money at it by doing so. It's the classic move if you're selling too much and not making enough and I think it's the best idea for you.
2. Start shipping through the USPS. Unless you're using a drop-shipper you should be taking that sort of load through customs and shipping by the much cheaper USPS. That will get rid of a lot of complaints right there.
If you are using a drop shipper, then I can't suggest anything, but you've got 8 months to find a better way or a new line of work.
