Worried, advice and prayers needed please

Hello to my semi colon family,
It's that crazy chick from England sonia, need so advice please as I'm worried and I'm starting to go back to thinking when I was first diagnosed back in Feb 09. Basically I did round two of oxi and xeloda, before I had treatment on the 20/7/09 I had blood tests and they were fine for treatment to go ahead.
Suffered from oral thrush so have had to stop xeloda for a few days, then it got really bad went to gp who diagnosed oral thrush and took bloods as per my oncologist request. But during the Tuesday night I had a fever and was admitted to my hospital, they took bloods and gave me stronger stuff for the oral infection, but my bloods were fine and I had no infection. The surgery rang up and said that they have to do my bloods again for my liver enzymes, as one is slightly elvated, it should be in it's 40's but it's at 120. So I'm going in for another blood test tomorrow, just hoping and praying its been raised because of chemo, the infection etc.
But as you all know and gone through this, your mind always goes back to when you were first diagnosed. I had a scan back in February, liver etc was fine, even during operation surgeon checked it was clear. I'm stage 3, with 10/11b lymph nodes being infected, tumour was removed. Had many blood tests since then, and they have been fine, just when I got the oral thrush and being on chemo, pain killers, depression drugs, I'm just worried. Please pray that its just because of the infection or nothing sinister, I just cant go through anything more, I'm weak mentally, still suffer from panic attacks. I don't know sorry for rambling, just wanted some advice.

Hugs to you all
Sonia
