Hi Sarah,
Spain is a wonderful place, but I am sorry to need to start with a reality check. There are simply no jobs to be had for anyone not fluent in Spanish these days. A branch of Iceland Overseas opened near us a couple of months ago, they received over 1400 unsolicited CVs as people identified them (correctly) as a potential employer where you might not need Spanish, they probably hired less than 100 of them so that shows how many are still looking in our small town. We are Costa Blanca not Costa del Sol but I am sure it’s no different, unemployment is rising daily, and bars etc are closing.
I completely get the need to start over at your point of life and really do wish you every possible success, but would advise you very strongly against uprooting yourself without some means of support, as you simply cannot count on getting paid work in Spain even once you master the language. Of course, you have lost your job in the UK so maybe it’s no different, and if you can get any kind of income this is a great place to be… I would just urge you to be realistic and think very carefully before burning bridges. Look at as many different options as you can and keep an open mind,
GOOD LUCK whatever you do..!
