What happens whenawheel bearing goes outwhile driving

In case it's important, my car is a 2008 auto Suzuki Swift. A couple of days ago I spun out in the rain on a roundabout (my tyres are bad, I wasn't speeding or being reckless) and I went up a gutter backwards. My cousins BF who is a mechanic said it sounds like the rear driver side wheel bearing is damaged. The car makes a not nice sounding growl from that sides tyre that's the worst from like 40km-70km but turns into more of a vibration than a sound at 80+ Unfortunately I can't afford a replacement anytime soon as I only just replaced my engine which was, internally, in horrible condition when I bought the car and seized completely after replacing the rocker cover gasket. (it has literally been nothing but a nightmare, I bought it for 6k AUD and have put in more than 5 in repairs) How long could I get away with driving it if it's at all safe to do so? I generally only drive to work which is less than 10km away but I need to travel around 50km tommorow but I really don't know if it's safe to do so. My cousins BF seems to think it should be alright but he is merely going off a description of the issue over the phone. Any advice would be greatly appreciated, thank you.
