trying to wean off xanax

I have been on xanax for yrs. It started when my father was diagnosed with cancer and then had a stroke. After 2 yrs..he passed away. I was raising teenage boys, taking care of mom and making all medical decisions for dad. I was initially given .5 dose 3 times a day..worked up tolerance over the yrs to 2mg 4 times a day. My life is calm now and I want off! Antidepressants haven't worked. Out me to sleep all day and I'm single with fulltime career (that I'll lose if I enter detox). I've weaned down to 1 mg 3 or 4 times a day (most at night to sleep). My heart still feels like its racing. I am so hyper and talkative, can't focus at work. My Dr insists on trying more antidepressants. I've been in 6 different ones and THEY MAKE ME DEPRESSED... almost suicidal. They are NOT an option. I'm determined to do this on my own. I quit smoking after 20+ yrs. I know I have willpower. I don't have addictive personality and can't STAND what xanax is doing to me. Is there ANYTHING natural that won't knock me out or depress me that will help? I've been on lower dose 6 mos now and only take dose when chest feels like its popping out or when I'm a walking zombie from lack of sleep. I DO have sleeping pills to take if necessary... Ugh

Actually I'm pretty great at relaxation and breathing from back in the day child birth classes it's just so hard to sleep and my heart keeps racing even though I have no stressors. Maybe it's just going to take a long time. From reading the other posts, it appears I was on a pretty hefty dose when it was at it's peak. Thanks for the links!
