Accidentally sent to my own receiving address, will I get back my bitcoins?
Bitcoin doesn't know that the recipient address is also yours. Therefore, while you sent the money to yourself, it looks like any other Bitcoin transaction to any other network participant. 

To your wallet provider (blockchain.info) it is obvious that you control both addresses, so they call it a "transfer" instead of a "send".

As you've sent it to your own receiving address, you should be able to see it counted towards your balance. If it hasn't been, get in touch with blockchain.info and request that they help you rectify it.
