You make it sound like you were forced to take up a job with FR/EZY...
If you had taken a second to think about it, instead of rushing for the first jet job in site, you may have realized that it would be more beneficial to wait for a non-P2F job. The loan repayments are irrelevant, you would have had to wait longer for the job, but you're saving yourself 30k in the meantime. With the likes of Monarch, Jet2, Flybe, all hiring in recent months, you can't say there weren't options, plus many more option abroad.
Avoid P2F! Nevertheless, good luck getting out of your self-dug hole.
