I know you regret it, but there's nothing you can do to change it. I can somewhat relate to what you're feeling right now, but not at the same degree, since your transactions are way higher than mine. When I returned to the Bitcoin scene and this forum, back in December 2020, I managed to recover two Blockchain wallets with microbalances left in them.

This is one of them. Honestly, seeing the transaction value with today's price did hurt a little.
