I'm currently working three part-time jobs (waitress, admin assistant and tour guide) and living with my parents. My contracted job as a curator, which is what I'm trained for, ran out last year, and since then I've been unable to secure anything in the museum sector. I'm desperate to get into full-time, permanent, secure work and start my life properly (I'm 25). I have been looking at other sectors too but nothing has paid off.
One of my friends works in archaeological excavation - not something I've ever done before - I work in museums, not in the field. She recommended me to her bosses and they want to offer me a 3-month trainee field contract. Although it is in the heritage sector, I have some major concerns. Firstly, it would mean the expense of relocating for 12 weeks with no guarantee of anything afterwards, leaving me with the very real chance that I'd just have to move back with my parents again. The pay is low (although that's not unusual in heritage), but would be just about livable if it wasn't for the fact that if I started mid-November, which is when I'd be able to leave current jobs due to notice period, I may not get paid until end of December at the earliest, but possibly January. This means I could be over halfway through the contract before I see any money. The jobs I'm currently in are equally poorly paid, and I have little in savings. I might be able to cover November but after that I don't know where I'd get the money from for rent or bills. The rent for the city the job is based at is ridiculous. Not London, but affluent old-university town. The areas of the business which I do have the skills to do (post-ex, analysis, archive deposition etc) I won't get anywhere near.
On the other hand, I don't want to appear ungrateful to my friend. This is the first proper job offer I've had in a year and I don't want my parents and friends to think I'm turning it down for silly reasons because it's not in the "right" sector. If it was even 6 months contract I'd jump at the chance, although the affordability of moving and living would still be a major issue. I was so happy when the initial message came through, then my heart sunk when I realised it was only three months temporary. My parents have been very kind and offered to help me with costs and living but I don't want to impose on them or take their money - they've been very generous in the past with university and letting me live with them again but I'm 25 now and I shouldn't be taking money from them (I do pay rent and my share of the bills!). But I don't want them to think I'm throwing the chance away.
I think I'm going to regret whichever decision I make. If I take it, I don't think I can afford to live and will beat myself up for it. If I don't take it, I'll look ungrateful and will beat myself up for it. On one hand, it would be lovely to have a full-time slightly-relevant job, on the other hand I think it would be a very expensive white elephant which won't really get me anywhere. WIB unreasonable not to take it?
I've had so many failed interviews for amazing jobs, but now I actually have a job offer it's one I don't think will work 
this whole year has been shit. I'm fed up of moving about and having to relocate every year. I'm fed up of working three jobs and still not making full-time hours. I'm fed up of living in my childhood bedroom. I just want something secure and stable that I can live off .
