Friendly advice: For someone who owns this much money in Bitcoin, you know very little about how it works. May I suggest you learn more about Bitcoin before you make a very expensive mistake?
Bitcoin addresses can't have a negative balance. It's impossible.
Blockchain.info has bugs, the website shows a negative balance after a double spend. There's no need to "refill" that wallet, and even if you would do it, that wouldn't change anything for existing transactions.
This is what I understand:
1. On December 15, you tried to send 11.23 BTC to 1MeLoYPNZbc4XfMi2PuhxWnATDnYD9VuMH, with a low fee.
The transaction above will never confirm, because the inputs are used in the transaction below. It will at some point drop from mempool, and be completely forgotten.
2. On December 21, you sent 1.24 BTC to the same address, and 10 BTC to a change address.
This transaction got confirmed and the funds were used again in other transactions.
The
unconfirmed double spend transaction that will never confirm was used as an input for other transactions. These too will never confirm, the original input has been used somewhere else already.
Your wallet should drop those transactions, and stop broadcasting them. Which wallet do you use?
Basically, your wallet is a bit of a mess now, by building upon unconfirmed double spend transactions. It depends on your wallet how you can best deal with this.
