Moving back to the UK isn't going to be cheap. If we want to move back we'd be looking at 7 grand minimum to move our stuff, our cat and ourselves plus the deposit and first months rent and some money to see us through (poss another months rent) until we found jobs. I appreciate it might not be quite so much for you if you aren't taking a lot of stuff with you and you wouldnt need to rent a whole flat but it's still going to a considerable amount of money to come back and start again. The anxiety of being financially fucked in a new country isn't fun. Its not as simple as just getting a flight back, you need to finance somewhere to live as well. That's a big ask on a family member. I'd tread carefully if I were you. Btw I'm not saying this to be a Debbie Downer, I'm saying it from experience. If I needed to come back to the UK at the moment, I just couldn't afford it. I'm pretty lucky that I'm happy being over here rn.
