There are a lot of prescription
assistance programs, like PPA, NeedyMeds, etc, but until you can get signed up for one, I sure hope that your Dr. can help you with samples. I know my Dr. is always had a lot of samples of various anti-depressants.
Good luck, and I sure would suggest not going cold turkey. I know when I lost my job, that was hard enough, but it's sad that we have to go without medical help and prescriptions because we can't afford them!
