Hang in there!
This is just a bump in the road and a great learning experience!
In real life, I have trusted the wrong person as well and have been falsely sued. After spending thousands of dollars in lawyer fee, all I had to do was to present the original documents that they forged to use to sue me and the case was thrown out without any further legal proceedings.
The lesson there - keep all important legal and financial documents in a safe place and don't talk without your lawyer present.
All the best!
