In Japan Financially Cooked

So I am a 23 year old male and I recently decided to take a trip out to Japan, it’s been a long standing dream to travel the world and I had enough money I believed and all was fine and well. I was going to bring my best friend but we got into a huge argument and long story short it didn’t work out. Recently the Canadian British Columbia wildfires broke out as since that’s where I’m from I got worried and well it turns out for good reason, my grandma was forced to evacuate had no money and no way to do anything so like any good grandson who loves his grandma I sent her everything I had which to be fair wasn’t a ton maybe about 6300 CAD idk what that translates to into USD but now I am in rough shape until the beginning of next month when I get paid for a project I invoiced for, any thoughts of what to do in the now?
