I worked in a pharmacy for 5 years (I had to quit when my suicidal ideation started to tempt me to steal meds for the purpose of offing myself), and can say that any decent pharmacist (in NY at least, I don't know the laws in other states) will go out of their way to make sure you have psych meds. If you can't afford them, ask the pharmacy cashier, tech or pharmacist. Often they know of programs that will reduce the cost. At my Pharmacy, we even went out of our way to help the people who were having complete rude melt-downs from not being on meds.

A pharmacy once filled my Effexor script wrong and I didn't know- was in tears all day until my significant other hauled me to the pharmacy and made me tell them I didn't feel right. They looked in my pill bottle and found they had filled it with extended release instead of my usual. They fixed it right then with many apologizes. I didn't sue, it was an honest mistake. Pharmacies triple check everything as a matter of course, but still mistakes can happen.

Always communicate your med worries to your pharmacy, they can help you.
