Benefits of quitting cannabis

I am a 60 year old mother and step mother to 9 children, grandmother to 11, one of whom I am raising with my husband.  After several frustrating and disastrous experiences with doctors, I turned to Cannabis about 10 years ago as it relieved a variety of symptoms of diseases I have struggled with for decades.  Long story short, I have, for several years, found this very useful and stopped requiring a number of prescriptions. I'm  always weighing the benfits agains the guilt and anxiety of doing something 'hidden' and 'illegal' - although my immediate family has been mostly very supportive.  At this point in time, I feel the smoking is affecting my health and am determined, despite the MANY false starts everyone else experiences, to quit.   It has come to the point that whatever benefit I  gain is lost in the negative health benefits, as well as

trying to hide it from growing and curious grandchildren, etc.  Just not worth it. 

My problem is that my family, particularly my husband, sees the great pain and stress

relief that it can be for me and gets very nervous about me quitting.  I had made it through several days of my last attempt only to awaken from a nap with a bag on the pillow next to me!  He thinks he's helping me and is disturbed by the amount of guilt I feel.  I don't want to go back to a regimen of prescription drugs that turn me into a zombie (painless, but zombie, nontheless).  I hope you see my conundrum and can offer some sound advice about how to convince people it's really beneficial for me to quit when they know it will mean putting up with a somewhat cranky, miserable me for a while    It seems everyones posts I've read speak to the stress and difficulty of the first few days (months? years?) and my repeated attempts are not encouraging.  I get very unbalanced.    Do I have any hope?  This is a scarey thing for me to put out here. Thanks - if anybody is listening.
