Do I have GAD?

Hi

I was diagnosed with OCD and anxiety when I was about 11. And this is how I feel - do I have GAD?
I feel ill - all the time. It's worse in the late afternoon/evening, which is when there's lots of people around. It has been like this for months now. because of my OCD I'm always panicking it's something serious like cancer or something. I have had blood tests, urine tests, seen an optician and a doctor, and my psychiatrist who is also a fully qualified doctor - and they all say that I am fine, apart from being short sighted and my blood test said that I have high prolactin hormone, which is because of the medication I take - Risperidone and Sertraline. That stops my periods from coming. If there was anything serious wrong with me it would show up in a blood test right?
So, I'm just worried mostly that there's something wrong with me. I do a lot of compulsions which tire me out so I am tired often. I feel ill constantly but I haven't thrown up - I used to have a serious phobia of sick but it's got a little better now. Is feeling sick all the time a symptom of anxiety? It's pretty much everyday and like I said, worse at night when everyone's around. I also feel sad a lot, like I just want to give up, because I can't cope with the worrying and feeling like this. My psychiatrist has assured me so many times that I'm fine, just anxious. What do you think?

Hi, rubeejs! I feel sick when I get anxious too, mostly nausea. Your doctor might be right.
