There are a lot of weird people on Spanish Expat forums, thats for sure.
Most are retired people who give advice due to there perceived life experience, rather than actual experience.
I always write about negatives, only because the positives are pretty obvious to most people.
I always advise that Spain will not improve life as much as people believe.
The issues in the UK are in Spain, if your unhappy with the UK, your likely to find out that the same/similar announces are there as well. Most expats find out once they`ve learnt the lingo.
Spain should never be seen as a long term solution, I `ve yet to hear from an Expat who moved, worked and lived all there life and died in Spain.
I was a migrant worker, I never planned to live forever in Spain it was an experience, not always pleasant.
I`m sure you`ll be fine.
