Do you have a working visa? Otherwise cost for a long term visa should be accounted for. Most EU countries allow for a tourist visa up to 6 months, but then you should exit the schengen area and stay out of it for some time before being allowed back in.
3000 for clothes seems excessive, but that’s me. You have your luggage with you, and unless you will move to extreme climates you won’t need that much money to buy clothes. It costs much less to have an extra suitcase each on the plane.
I don’t see any Import taxes for your container. This might depend on your destination country but it could be substantial.
Also, if you think to buy a car, make sure your driving licence is valid over here. You might need to set aside money for a new valid European licence.
The first time I moved away from home was to go to university in a bigger city within my country.
The I moved to another country for 2 years and finally I moved to a third country permanently (it’s been 12 years).
Well, life has kept moving on in my home town. Frienda got married, had kids, died at young age without me being there. It’s part of the choice I have made.
At first it was always me getting in contact when I was back in town. Then I got angry with my friends because they were not making any effort to keep the relationship alive.
It took me some years to figure out that’s life. Some friends and family hurt more than others but I am still in contact with a handful of them, and that’s fair.
Life moved on for everyone.
