What Causes Anxiety, Depression And ADHD While On Trazadone And Prozac?

Question: Good morning I am a 52 year old woman who had diagnosis of anxiety, major depressive disorder, ptsd and adhd. I am working with my psychiatrist to get off the xanax as i have been on it for over 15 years at .5 4x a day. 2 months ago we tried to reduce it to .25 4x a day but it was not working so last month i got a prescription for valium 10mg bid and 10 Ativan 1 mg prn. I picked these up on September 2 but still had some .25 xanax. Everytime I would feel physical withdrawal symptoms my blood pressure rises to the 140 to 150 over 90's range and this causes a headache heart palps dry mouth etc. I only have 1 Ativan left and have not taken a xanax for 4 going on 5 days today. The problem is i take the valium in the morning when i take my adhd med so i don't get hyper but by 12 or so i am in the throws of severe physical withdrawals. I try very hard to work through them and not take the xanax but it leaves me ill for the rest of the workday until i cn get home and take my valium at night. How long does it take for the physical withdrawals of the xanax to subside as it is very difficult to do during work hours. I am fortunate that the Dr. and office manager i work for are very supportive. I am on Vyvanese 60mg, prozac 60mg, Trazadone 150, ambien as well as blood pressure medication. Any suggestions am I doing this right
