Help me meet the love of my life.

I asked my mum to make an account on this website to arrange money for a trip.

My name is Sebastian, I'm in long distance relationship with my girlfriend. I'm 16 and she's 17, almost 18.
I'm from Portugal and she is from the UK.
I'd like to be able to go see her, for the first time, this year, in December.
I've tried arranging money playing in the streets, much to no avail.
I'd only need money for the flight (30dez-6jan) and for a hostel room. Other expenses are not necessary, but would be appreciated. Right now would be the perfect time to buy the flight since they're cheap. They're going for around 150 euros roundtrip tickets. But I'd also need money for food. If you could donate something within your reach, I'll be very thankful.

Please help me be with her.

Thank you.
