It's tough out there and it's completely normal to have a lot of interviews before finding a job. Myself and a lot of my PGCE friends have had at least 6 interviews minimum - that is how difficult it is. Schools have their pick of candidates and there are a lot of people who are ex-students and have worked at a particular school and so it makes it even harder, as they are often first-choice for any jobs as the school know them. Just keep trying as lots of people are in the same boat. There are a lot of success stories on here and many of these people have been in the same situation as you. Keep trying, perfect your interview technique and try and feign confidence on the day of the interview. If you act it, you will eventually feel it! Family members/friends don't understand how difficult it really is for unemployed teachers so I feel your pain regarding the situation with your girlfriend. Good luck and I hope you get something soon.
