Swapping BASE ETH for SOL

Hi, All. Feeling hopeless today. Yesterday, I swapped ETH for BASE on SuperBridge to buy BASE coins on a DEX. Now, I want to swap it back to ETH to return it to my Coinbase account.

I tried a dozen different bridges + tried swapping directly in my Coinbase Wallet to no avail - I can't get a bridge to complete the transaction, ~$2,500 worth.

I added $150 in ETH to my Coinbase Wallet to pay for fees after getting this msg: "The total cost (gas + gas fee + value) of executing this transaction exceeds the balance of this account."

After doing so, I tried again, this time a $10 test transaction. However, this morning, the transaction status is "Dropped" like several before it.

Now, I've given up on swapping for ETH and trying to swap BASE for SOL using Jumper Exchange. Yet, 4 hrs later, the transaction is still in process. What am I doing wrong?

I'm just trying to recover my funds, but losing confidence and hope. I understand if the ETH network is too busy, but why can't I swap my BASE for SOL?

Presumably, I can't simply return my ETH on BASE to my Coinbase account. Any suggestions, I'm truly adrift! Thanks!
