Anxiety around medicine time. Condition?

I am on anti anxiety medicine since a year now. Currently taking ciplar la 20 and beta anxit 20. I get tightness in head around my medicine time of day , it gets better when I take the medicine. Also i feel same tightness in head and slight breathlessness after pooping. This pooping thing doesn't happens every time, if pooping is of urgent type or if i go to poop frequently like in gap of a hour (specially in morning time). Some days it gets very bad that even it takes 4-5 hours to calm the body. Is it normal with anxiety disorder or my medicine is not enough for my condition??? I did check my heart rate on mobile app like mine and most of the time in lying state it was around 75-80 and sometimes rarely one or two times a day if i move around or wakes up after day sleep it goes Max upto 100. My ECG told sinus tachycardia and echo is normal.
