Anxiety

I was wondering if my GP doctor would prescribe me something for my anxiety and sicknesses I got diagnosed with cancer on the 28 July as got a biopsy on a lump on my throat now a have had a biopsy to find the sourse as nothing is showing up on the pet CT scan so I had a bit of the back of my tongue took and a look behind my nose there 80% sure they have found the source I am just waiting to hear back from them if they have found it I will start radiotherapy but if not they will have to do another biopsy a more complicated procedure so all this waiting about is so hard I am ill with anxiety and wake up feeling sick I take panic attacks the lot I hope my doctor can give me something to give my mind a rest as it is stopping me doing or going anywhere I have just locked myself away from everyone witch isn't healthy
