Invested 55k into crypto

I invested 55k into crypto (more like gambled it) I’m currently down $40k it’s a pretty crap situation I’ve put myself in, I can’t see any point in selling now. I have good earning potential at my job but I’m depressed at the thought that amount of money is practically gone now as it was my entire house deposit for here in australia, I’m 25 years old, just feels like I put myself back to 0 and have to restart all over again. Dunno I just wanted to vent or get advice / hear someone else’s story I guess and try deter anyone else thinking of putting their life savings into shit 😆
