Is medication proper? I am going wrong?

I was having anxiety attacks and I have a history of mild depression. Doctor prescribed me amixide h, dveniz 50, rentac 300, migon 10mg at 8pm. And dveniz 50, ativan 2mg, mirtaz 15mg at 10pm. I took these medications but I started having other problems like diarrhea, sensitive ears, tingling at left side of my arm and face, high level of gastric problem, muscle cramps, and sleep disturbance Then I reduced my medication to taking rentac 300 in the morning and before dinner. I took amixide h before dinner, and dveniz 50, ativan 2 an hour before sleep and mirtaz 15 just before going for sleep. But i still have problems like gastric problem which makes me feel heartburn, also i feel burning sensation behind my head and stiffness on my left side of face. Also burning sensation in my ear portion too. I still get severe leg pain usually in left leg but sometimes in both. I am very confused. Where I am going wrong? I need a guidance on how and what should i discuss with my doctor.
