Recently I Filled A Prescription Of Xanax, Which I Happened

Recently I filled a prescription of xanax, which I happened to lose today. This is the first time I have ever lost my anxiety medication. I suffer from PTSD and have an extremely high level of anxiety at the moment. My fiance is pregnant and I am looking for a new job, and we will have to move. Do you have any suggestions of a supplement I can take, a way of refilling my prescription, or any other advice. I would greatly appreciate any advice you could give me.
