I too am massively stressing out about being able to afford FFS. Saving up over several years for me just isn't an option - call me impatient, but I want it done by the end of this year at the latest.
I'm a student and will be for another 4 years so, even if I get a part time job there would barely be anything to save, and I've kind of mentally come to a point where I can't stand not looking how I should anymore and it's having a hugely negative impact on my life. Wish there was some kind of magical solution, alas there is not.
The only thing I could suggest to you is a loan if you're able to get one, it seems like the easiest way to do it. If it were a choice for me I'd do it straight away. Otherwise, try to hang in there and keep your motivation going!
