I felt the same when Steve's treatment started and all the way through it. Still to this day, almost 6 months (can you believe 6 months already) since treatment ended I still feel anxious, nauseas, you name it. Always worse before any doctor's appointments.
Glad you have found this site. There is some great information on here and plenty of wonderful people who will show you that what you are feeling is normal, as we've all been there.
Personally from a carer's perspective. I think both carer and patient are pretty crap. Both bring with it there horrors and there pains. Not having been a patient I can't say for sure but from everything I've seen over the last 10 months it doesn't look to wonderful. But also from what I personally have been through over this time, it certainly wasn't a bed of roses. To me, both Steve and I have cancer. Just each one of us has a different part to play in kicking it's butt.
