What can I do if my wife filed a divorce case that is full of lies?

My wife has filed for divorce in her petition falsely states that I am a known meth user, I have no arrest records nor is there any evidence to support this claim. In addition, she is requesting sole custody of our three children and that I pay for her attorney fees and child support, she said I had superior earning capabilities as opposed to her state teaching job in which she receives a nice salary plus $1200 per month in health insurance and $500 into retirement plan, The teaching job which she recently acquired only after she abruptly quit our family business and sent it into a tail spin. She ran the the marketing and accounting as well as customer service, She was the company. She left the company after running it since 2004 without notice and without training a replacement for running the day to day operations as the general manager and CFO, since she left the company I have been struggling to keep it afloat and have been virtually made homeless from the business tanking. I held the family together while she went full time to get her masters degree and I paid for the family needs and she acquired loans for the schooling. Now I do not know how to respond and I can't even afford an attorney let alone Food. I suffer from PTSD and Major depression and rely on her medical benefits for my health and rely on her medical insurance and support which will be terminated upon the divorce, can I seek temporary spousal support? In addition, she failed to list that she is the president of an Oregon corporation on her income and assets list. She is unaware that I have this information, last thing is, she had a reposition company take my work truck that I used for business. I, which as a couple, we borrowed $2500 from her family trust to purchase the truck along with funds I put into the purchase of $7000 dollars total being $10000. I was not given notice of any of this the payments were made on time. According to the portion there is restraining order not to move assets.
