Hope today goes well Jenna, I agree with everyone else, try to stop putting as much pressure on yourself, I'm sure your doing an amazing job, I understand it must be extremely hard not feeling like the jobs yours, but you never know if you build relationships with the schools they'll ask you again when they need cover or they'll also think of you when a full time position comes up. I know that doesn't help you so much right now, also the nanny job sounds great good luck I'll keep my fingers crossed for you. My boyfriend is in a similar position to you, he's a secondary school teacher and really wants out of it, I think its mainly the school he's at but a lot of it is all the red tape, he's applied for lots of different jobs and it really gets him down at times.
Really hope he gets something soon as its horrible seeing how stressed he gets, it does spill over into his personal life as well. Which I can understand as well, I did the same when I was unemployed and volunteering, I cried for a whole day when I didn't get that job I was expecting and I think I would have gone on for longer if I didn't have that school trip that I'd already said I'd go on with little one's school.
Sorry I'm ranting a bit about nothing there, hope you have a good day today anyway.
Joanne, I'd go for the interview, it'll be good experience and you might not get it anyway, if you do get offered it you can change your mind after having a proper think about it. Why don't your parents like the idea? My mum is really against me becoming a slimming world consultant but I'm still going to look into it (they might not want me or I might decide I don't want to do it) but I'd rather look into that rather then just sit around waiting for something else to come up and accept me. Oh and as well another thing about my boyfriend, he's found another job which he's not to sure about, but like I said to him, if he applies for it then he can always change his mind, whereas if he doesn't and he changes his mind its too late at that point
