Life become very worse after landing in Sweden

And yes.. Europe is very expensive and hard... And in Sweden, to find a rent accommodation is almost impossible, above all in big cities in South. Only buying is possible, but to buy, you must have a lot of money and so, a good job, because if you have a "little" job without high qualifications, it will be too hard to survive and your family won't be able to come with you, because you must have enough money for your family can live without social allowance. What kind of visa do you have??? Because you can't come in a country to look for a job like that. You must find a job before to come or get a jobseeker visa. And for that, you must have enough money to live for six months...

It's rude but fact....  You will not get regular accommodation in absence of job. Why did you migrate at first place without job in hand that too with kids.... 
Sorry for not coming with help proposal....

Hello
I am saddened to hear about your situation. It is difficult to be in such conditions with wife and family. I can only imagine. Sweden can be very costly and finding accommodation is very difficult and also expensive. The only way to survive if you plan to move to Sweden is to in the case of a student, come to Sweden with enough money to sustain you, before you get there. So for example if you plan to live there for a year, you should find a place to rent before you get there, like online and have enough to pay rental for the whole year. You need to plan beforehand. Making sure you can financially sustain yourself in case you don't find part time work as a student while you are there. Money for day to day expenses, finding schools for kids etc. All this you should have and do before you leave your home country. When you arrive you can then take your time to find a job. After a year, if you haven't been able to find work, you go home if there is no opportunities for you in Sweden. At least you will have managed to look after yourself and family while there and less pressure on you to find work because you have enough money. This is the best route to migrate if you are not migrating as a person who has a work permit, unless you are a refugee and can get a bit of assistance from government.  My advice, check online to see if there are organisations in Sweden helping families in need or difficult situations like yours, or if you have money available check on this site Residensportalen, you can Google online: Residensportalen Sweden,
The other advice if the situation seems impossible and financially its difficult, you may need to go back home and then see how you can prepare and return to Sweden in future. Also try speaking to people from your community/ country. Go out there try to make contacts, tell people your situation and you may find someone who can assist you.

I hope everything comes right.

All the best
Mariam

I Second that!
