I only hold like 25 BTC, and I already lost 10 of them, in three fucking days.

I am the worst gambler in history, what reason is there for me to live?
You have already lost around 40% of your bankroll so you better stop immediately.
No you are not the worst gambler actually you fell into gambling addiction which make you lost whopping 10
BTC in 3 days. But you should now realize it and move on with remaining 15
BTC. Stop gambling and stop trying to recover your loss with your remaining bitcoins.
Good luck
