Help to tide through a dying business

We are a startup business running since Oct 2018. Business has been dying since 4 months after startup, we have been losing 4 figures every month.

Ending up in debts, we are now working full time to fund the losses of the shop. We tried to request to exit the mall but to no avail. We could not till we complete the lease term of 3 years.

We are completely burnt out running the business and working full time. Do not have anymore freedom and relationship is at stake because of the business.

The mall as a whole is a dead mall, and management is not doing anything to aid the tenants in here.
