Hi sullen, I wanted to welcome you to Healing Well forum first off. There are so many supportive people here always willing to help and lend advice, I do hope you continue to return.
Do you have a primary care physician that you go to or psychiatrist? If so, you can speak to them about your lack of insurance and most times the doctor is willing to provide samples of an antidepressant. They get them for free from the drug companies anyway. This is mostly going to depend on what you are prescribed though. Also, now most of the major companies that make antidepressants are doing prescription assistance where they will either pay part or all of the cost of your medication depending on your income level. This I do believe is for people who don't have insurance coverage. They are making it very easy now for people to get help for depression who cant afford the medications.
Please do let us know how your doing...Take care.
