Contract help

So I am new to travel nursing and had an opportunity to get a position in a location I wanted. However my recruiter told me because I took too long responding back to her, the position I was offered was filled.

I felt like I was rushed into deciding if I wanted to accept the job. I had so many questions and it was during the holidays so she was out of town and sick. I wanted to go over contract details with her and to have specific requests written in the contract. I've been reading reviews online telling all travel nurses to get things written in the contract and specified. (What things do you mean... I tried to ask my recruiter to put into the contract that I not be charge nurse, if I could request some days off for a wedding and scheduling requests,.. But she said the contract is as is and cannot be changed. Is that true.) And my recruiter wouldn't let me go over the contract before I officially accepted. She said I can see the contract once I accept. Does that make sense?!??

Please help

Thanks!!
