Sorry, camposol, but I know you don't like it in Spain. You obviously miss your family, you have bought the wrong place in the wrong area and, I've said it before, if I were you I'd have packed up years ago and stayed near my family with, maybe, the odd excursion to somewhere exciting like Skegness. However, I must take task to some of your points:
Sahara rain which leaves everything dirty and streaked
You obviously live in the wrong area. We sometimes get the sandy rain but it doesn't leave it dirty and streaked. Only the car is a nuisance and it doesn't take long to get it off.
Lack of regulation
What lack of regulation? Most Brits seem to complain of too much rather than too little and are always trying to find ways to get around the rules.
Police tolerance of UK plated cars owned by residents
Totally different in this area. Foreign (not just UK) cars are regularly stopped for document checks. Again, not a Spanish problem but the Brits trying to get round the rules.
high electricity costs
I might have agreed with you a year or so ago. Electricity in UK is now higher than Spain. Since the recent rises, average price per Kwh is 14 to 16p compared to Spain 16 cents. If your bills are higher in Spain, you are using more electricity. Simples.
complex tax laws
Why complex? You mean, as a Brit, you don't understand them. I'm sure a Spaniard would have just as many problems understanding the eight hundred and odd pages of tax rules in UK. Get someone to explain them to you. They aren't that difficult.
High costs when selling houses-estate agent's commission, plus valia etc
I will agree on that. However, UK estate agents are no longer cheap, either.
Conflicting advice from professionals
And you don't get that in UK? Speak to three solicitors and you'll get three different answers. The problem here are the pub experts who spout incredible rubbish and people take it as gospel. In all my dealings with professionals I've had the same advice. From obtaining certificates, buying a car, changing driving license and so on. It's the Chinese whispers that make things so complicated. Look up the UK FCO advice pages. They don't vary unlike advice on whether red wine is good for you or not or whether you should take an aspirin a day or not which float round the UK.
Lack of care for vulnerable people-homeless etc
Seems to be a problem all over. Go to any city in UK and see the number of people sleeping in doorways.
Lack of hygiene
Now, you just made that up. Have you been to a loo in a pub in UK lately? Plumbing here has improved immensely in the last 20 years if that's what you're on about. And, remind me, where were all the MRSA cases in hospitals? Our roads are cleaned 3 times a week, our dustbins emptied every night, not just once a fortnight. The streets on our complex are cleaned and swept on a daily basis.
Inconsiderate, impatient careless drivers
Have you driven in the UK in the last 10 years? Getting flashed on motorways, people using mobile phones, not indicating, pulling out at motorway junctions etc. It's just as bad there but there are so many more of them.
Lack of respect for laws eg smoking
Do you mean in pubs and restaurants? Again, you must be living in the wrong place. Strictly enforced around here. They even took one bloke out smoking an electronic cigarette.
Invaders in huge camper vans taking over car parks
I regularly travel from Alicante to Cartagena. I have only ever seen this once and the local council has just moved them all on. Unlike UK when the travellers move in.
Spitting and littering;chewing gum ruining new paving
Just like any big city in UK. Dirty, litter strewn with fast food wrappers and boxes all over the place. Chewing gum is a menace and spitting seems a new craze.
high winds
Again, happens anywhere. You must live in a very sheltered spot in UK if you don't suffer those there.
damp, cold winter- freezing bathrooms (yes we all know it's not as bad as UK)
And now you are making it up. It's been over 20C every day this month and only dropped into single figures at night on two occasions, it's rained here once this year. Last January was exactly the same. Damp? rubbish. Freezing bathrooms? What would you do in UK? Stick some heating in there. So do the same here. FGS go and buy a heated towel rail if it's that bad, they cost the same as an electric light bulb to run. People moaning about cold houses and so on should get off their backsides and do something about it rather than say "ooh, it's all Spain's fault, nobody told me it got cold in the winter and hot in the summer." I spent thousands on double glazing in UK. If it got that bad I'd do the same here.
Now, I shan't be replying to your posts. You have problems and they seem to weigh on your mind and you appear to blame Spain for every little problem. I have absolutely no idea why you moved here in the first place but you've obviously made a mistake. Cut your losses, go home and live off benefits and your family if it's so great. You're simply exacerbating matters and letting everything get to you. (no charge for the Frasier consultation, by the way).
