Of course you are dis-empowered, anyone in your situation would feel the same.
I've been trapped abroad. I had money, a ticket home, but i couldn't have physically got my son and my luggage out of the building, let alone call a cab. The airport was 3 hours away.
Sod the sunshine, it's only nice if you are free to enjoy it, or if it doesn't burn you from only 30 seconds of exposure. Give me FREE rain in a safe environment every day of the week!
My advice to you love is to try to calm yourself a little, take a step back and see what you need and what needs to be done to achieve it. Approach this with cool calm and from an organisational perspective.
No, you probably can't pack a bag and get out this week. But you can work out what you need to do and we can help you organise/plan/think through stuff if you need us to.
So if you want to come home, which would be the best alternative for you, as support is easier to arrange, then start to think what you need to do.
Accommodation: Can you give notice to the tenants? Or are they still in a fixed period? Would the rent they pay be enough to cover the mortgage there AND a rental property for you, if so, leave them there!
Money: Could you get enough together to come home and not work for a while? Could you pay 6m rental up front?
School: are there places in schools nearby? could you enquire about potential spaces.
Start asking questions and inform yourself, then the task ahead of you will be easier as you will have some answers.
In the meantime, while you are planning what to do, we can help you by hand holding, and suggestions of where you might get help in the area you will be returning to.
Take one task at a time and just find out what your options are in each of these areas. Don't look at the whole task in one go, it's too daunting. You can't stay in this jail just because of schooling or the dad's access to them, he can come home too you know? It'd be HIS choice.
You can do this, you will be OK.
