Depression and anxiety....

So I have been dealing with depression and anxiety since I was about 15-16 years old. Finally I went to the doctor again after 6-7 years to get put on some medicine for it. My doctor wrote me a prescription for Cymbalta... I took the prescription to the pharmacy and then went shopping... A few hours later I went to pick my medicine up and was told my medicaid wouldn't pay for it and it cost $600... My doctor told me it would cover the medication.... Idk who to believe but I just left the pharmacy pissed off.... I was trying to help myself, my marriage, and my job by getting help with my depression and anxiety, but turns out I can't afford it... Idk what else to do.... I feel like it has gotten worse... And what doesnt make since to me my husband has the same medicaid as me and he takes Cymbalta and his medicaid covers it... I'm a lost of words... The person I talked to at the pharmacy is my husbands ex from high school... Do you think that has anything to do with it???? Because if that's the reason I will hurt her! She thinks she's crazy!! She's told me in the past "I will get Nate back. Don't mess with me I am crazy!" I was like seriously? You think you're crazy? Idk though.. But she is really pissing me off... Nate told me to call the doctors office and see what the problem is... What do y'all think?
