Smoking

So my husband is a really great guy not controlling at all just a wonderful person. I have a long history of depression and anxiety and I've done the prescription meds and I hate them. I know its terrible for me and gross but smoking ciggerattes is the only thing that helps.. My husband keeps telling me I need to just quit but its not that easy. Should I quit or should I keep doing the only thing that keeps me from having anxiety attacks all the time?
