Toprol-XL and severe abdominal pain

Update - 7th day with zero Toprol. Feel just awful... Breathing has not improved, tight band feeling around chest keeps coming and going like before. B/P spikes, headaches, etc. The Diovan (80mg) was making me cough and making chest tightness worse - so she tried me on Dyazide - made me dizzy and sick to my stomach. This has been just one of the WORST experiences of my life. I was SURE all my problems were related to my (4) years on Toprol - but on day 7 with NO TOPROL and not feeling better I am depressed, discouraged, and just want to curl up and cry and cry and cry. I have ended up in the ER three times since the weaning began - once for breathing, once for pulse (over 215) and once for severe abdominal pain. My family thinks that I am 'mental' and that it is all in my head???? I cannot take much more of this.....
