Man i'm in the same boat. But at the end of the day i don't want to go into any career (Pilot) which will leave me and my family with a great amount of debt and a burden.
The question you need to ask yourself is it worth spending 80-100 Thousand pounds!! Then not even having a job at the end, and probably flying for low cost carriers or cargo that you'll not get great pay, great hours or anything. No career is worth that.. especially in the current climate where routes are being trimmed.
May the force be with you and i hope you are happy with whatever choice you take.
