Is this anxiety or something more serious?? Scared!!

I've been feeling ill since the beginning of March. I've got pain in the one side of my head, I'm light headed and foggy headed daily and I mean daily it's getting me down now, I have a whooshing sound in the same ear the head pain is on especially when I'm lying down. I'm seeing a cardiologist this week but I feel it's something to do with my head. I've asked my doctor to refer me to a nurolagist and she said no because it's health anxiety. I feel like I cant get passed her and I really don't know what to do. I'm only 29 so my quality of life shouldn't be like this at such a young age. I feel so ill. Somedays I'm shaky. Doctor started me on fluoxetine I'm on day 22 today but I still feel the same as I did when I first started them if not a little worser. Anyone got any suggestions I could really do with the help. I'm so frightened incase it is something more serious.

Nothing you have said gives reason for her to send you to a cardiologist. A neurologist sounds a much better option and they normally start off with thorough physical examination and blood tests. Doctors who dish out Prozac so easily are best avoided. .  

Most my doctors I've seen keep dishing out anti depressants to me. I feel so ill. I don't think this is anxiety : -(
