Help needed- stranded 18 yr old far from home homeless

Hello my name is Coral Lumm and I'm reaching out for help because I don't know what else to do.

I'm 18 years old and I was traveling to Canada to visit friends and family from Australia. I was traveling to Canada to meet up with my partner and see around Canada. I was denied entry at Vancouver International Airport and now I'm stranded in the UK with no resources even though I'm a citizen.

I'm at a lost and I have barely enough money to get myself food for tomorrow but I fear I'll end up on the streets without any help, and I'm terrified of what comes with that. I've tried all government resources with no luck and I've been given three months before they'll even consider helping in any capacity.

It's been days since I've had a proper meal or even been able to wash my clothes. My partner's family have helped where they could but the resources have been exhausted. I'm absolutely petrified of ending up on the streets as I've seen what's been going on in the news all over the world.

So I ask, please if you have any money you can spare please help and donate so I don't become homeless. I'm so scared and I have nowhere else to turn, so please help where you can.
