please help

You don't really offer info, so I don't think that you can realistically get more help in here.
As just said, all we can do now is to contain/limit the damage, since you may be targeted with a wider scam.
And we are not making fun of your sadness. We try to offer you a cold shower to help you wake up to the actual reality.

Get your friend and see overview in detail every step you've done, maybe you can follow the fiat. When you have significantly more info you may have a chance for more help, although I think that:
1. You've got scammed and if crypto is prohibited in your country you may not stand a chance to recover your loses.
2. You are not telling us the whole story/truth. A small house in a normal place usually worth much less than 20 BTC. I may be overly generous even with 5 BTC.
