It depends so much on your personal circumstances, alternative career prospects, commitment to flying for a living and much else. Thus, it's hard for an outsider to advise you. All I can suggest is that you take a large sheet of paper and write down all the things that incline you to persevere on one side and all the reasons for calling it a day on the other. Look hard at it and have a long think. If it's pointing to calling a halt, end of story. If you convince yourself you want to continue you will have to come to terms with taking on an enormous burden of debt with no guarantee of a job at the end of it.
Flying isn't the job it was, and I say this regretfully after thirty five years in the business. If you have an alternative that will give you fulfilment and pay the bills ask if you really want to spend up to £50K for the privilege of working yourself to a frazzle with a low-cost carrier. Some do and there is still enjoyment to be had but the alarm going off at 0300 on a regular basis soon loses its novelty.
If you're mad keen to fly, go for it. Most of us have been there and we understand what drives people. But go into it with your eyes open. It's no bed of roses. Good luck, either way.
