I need help

Hi everyone, I been in the market for years but today I made the biggest mistake in my entire life by accidentally sending all my usdt from my account on the AscendEX exchange to the usdt contract address instead of my wallet address and i used the ethereum network and ive lost all and it's literally all have rn! Has anyone faced this issue before? And i would appreciate any advice on how to recover the assets? And I really hope this never happens to anyone here because it's very stressful to lose it all with just one mistake like that!
