Having lost some Bitcoin recently via a lightning experiment I understand your feeling but also we can tell anyone that the Bitcoin you lost was the necessary step in order for you to appreciate how scarce it really is. You can never buy what Satoshi, himself stacked because he believed more than you. You can't get it back at the price you bought or mined. You can't. But you can stack today and use every means of protection and respect for this truly scarce asset and manage it better.
Ultimately we are here to live as humans and not stack Bitcoin. We are here to try and help others but also to help ourselves by helping others. If you had a big stack and it's all gone maybe you didn't invest in the education, skills, resources and values needed to appreciate Bitcoin.
I have to accept that myself. But I also accept the the years of mistakes and learning have made me better at managing, helping and then accepting when things go wrong.
Today if you are standing on zero you can work or buy more Bitcoin. You can build your stack and stack some goals.
Or you can give up and let someone else rug pull you out your family in the future.
Own the mistake.
