Did one of you sweep my brain wallet?

I feel sick. I bought half a bitcoin when it was at 800. It was worth about 8500 a couple days ago. I decided to get it off coinbase and into cold storage because I thought that would be safer. I didn't know what I was doing. I'm incompetent and had no business taking it off the exchange. I made a brain wallet with a phrase and sent it from coinbase. I realized while it was processing how dumb that was and made plans to quickly sweep it into another safer wallet as soon as it cleared, but coinbase took so long to process it that I fell asleep. During the night it transferred and half an hour later the balance was swept to another address.

I know it's a long shot, but on the off chance one of you is a robinhood and swept it up, thank you. If this is a thief, this really hurt. I know I'm an idiot and got what I deserved but this hurts.

The transaction ID is: 9e6dec67246e4e2785edc9d7d15b089f700c65b6184d248c6b2cbc50dc3df8b1

I'm at a loss of what to do. Sorry if this shouldn't be posted here.
