What can I do if a company hired me then changed their mind?

I am working in a company and their management is the worst. They made an interview in India and called me.

After calling me here, they again made interviews and made me work for 1 month. And now, they're telling me I am not capable of work and they are mentally torturing me.

I have given them 1.5 lack in office in India and here they are not paying me any salary. I am going into depression as I am not getting any solutions.

The only solution coming to my mind is a suicide, I don’t have any other options left. I have taken money in interest and people are daily coming to my house for money.

Please guide me in a proper way on what I can do.
