Suggest Treatment For Symptoms Of Vertigo

I have been diagnosed with Vertigo few months ago. During this time I had palpitations behind my head. The fear was that I had aneurysm since my mum passed away with something similar. However, i had a CT scan done and MRI twice for head, neck and brain. Nothing was found. Now in the evenings I feel weak and few weeks was having palpitations in my throat. I feel I have difficulty in breathing, throat get dry and then i want to vomit. My legs get a tingling sensation which then makes me weak from bottom to top. I feel i will collapse. My whole body starts to shiver and i have put on lots of warm clothes. Recently I had a chest xray done but no issues. My GP says I have anxiety and has diagnosed me with some tablets. I am still not satisfied that i have anxiety and scared especially in the night. I feel i am not living a normal life. SOmething is wrong but yet dont know what is wrong. I need help, I am going for yoga classes and other therapy. Is this going to help, dont know.
