Just lost 99% of my ETH due to writing down the wrong seed phrase

I won’t be responding to any DM’s, so scammers can go away

FIXED! Turns out I had opened 4 accounts, so I had to add 4 accounts before my "new account", holding my ETH and MATIC, came up! Thanks so much to u/seb7mad, u/mbdtf95 and u/Ill_Buffalo_8644 for walking me through it!

So, I’m not used to MetaMask, so hopefully my story will help others not lose their funds due to unnecessary confusion. I’m use to the Cosmos Ecosystem and the Keplr wallet.

The situation I had was, once MOONs went up in value, I wanted to trade around on SushiSwap and try to get more MOONs.

I had a few “accounts” open on MetaMask, mostly random wallets I had opened while I was still learning how seed phrases and private keys work (apparently not well enough). However, I also had my old “account” and my new “account”, which holds my ETH and MATIC.

So I went to the appropriate, new account, made sure it had my ETH and MATIC, and then went to “reveal secret recovery phrase”, and wrote my phrase down to ensure I had it, for after I traded my MOONs.

I went about my business trading my MOONs, and then today I was going to get back into my ETH/MATIC wallet to have it back on my MetaMask. Low and behold, the seed I inserted didn’t have any ETH or MATIC in it. Then I looked at the transaction history on Etherscan and Polygon Scan, and wouldn’t you know, this was the old address. The seed I wrote down was for my old account, not the new one I had opened up.

I know I am to blame and I should have been more careful, but I really am so lost on why the hell MetaMask would give me my old accounts Seed when I know for a fact I was on my new account when I requested my “Secret Recovery Phrase”. It’s just so devastating. I really feel like a moron but I’m low key mad as hell that somehow I wrote down the wrong seed, I’m completely lost as to why that happened.

Anyone who knows more about MetaMask who may be able to advise me on what I did wrong (obviously wrote down the wrong seed, but how I did it) please let me know. Hopefully it helps someone else not screw themself the same way and gives me a learning lesson.
