EEG abnormal. And changing my lifestyle!

I am having this sharp headaches from 2 weeks after having fever.it was only second but sharp and it is back of head or middlee..I went to neurologist and had EEG and blood test.she said EEG is abnormal and crp and esr levels are high.maybe infection is still there after fever and prescribed antibiotics and headache tablet.i had anxiety issue past 2 year back.is this headache because of that anxiety issue or is that because of infection.she also prescribed anxiety tab.i also opened eyes and moved a little while taking EEG.does that make any difference.how can I take care of now at home I have two kids.should I need to take anxiety pills again or is there any way to get over this by doing meditation and changing my lifestyle
