I am on SS disability and have medicare A.B.& D.

My husband is now disabled due to an emergency quintuple heart bypass,he almost died and My prescriptions were always covered under his BC/BS he had through his job.Now I only have medicare D-Rx America.I was told today when i tried to renew my prescription at walgreens that it and my nexium were each going to cost at least 130.00.I have been on these meds for over 2 years and now am forced to suddenly drop them cold turkey.I am the only income and my disability is only 765.00 because of the 96.00 i pay for my medicare part b premium.Can you help me at all? Im really worried about dropping this med .i really need it and it helps me tremendously.Please help me!!!!
