However, I don't know what will happen with your bitcoin, I feel the same, my transaction stuck for weeks now. I thought it will be cancelled and my balance on wallet will be back, but it's not.
Tramsactions don't expire; most nodes only forget/remove them from the mempool including the wallet that you're using but that doesn't mean that these transactions aren't existing somewhere on other nodes. Accelerators would still work, or better yet you can replicate the transaction by applying proper fee bumping.
Next time, pay the ample amount of fee in order for your tx to not get stuck in the limbo and give you headaches. In the end, you'd still pay these fees so better do it earlier.
