Oh dear, you have some reasons to feel anxious. Once you have cancer you become hyper-vigilant about
your signs and sx that something may be wrong.
A few things do seem to help reduce the intensity of hypervigilism. One of these is exercise, which helps to burn adrenaline and release feel-good hormones at the same time. Another is relaxation, or forms of yoga or meditation. Breathing techniques are also useful and some simple techniques such as breathing in slowly and deeply, holding for four seconds then slowly breathing out as though expelling more air than was breathed in, may be helpful if anxiety builds as a result of perceived threats.
Steroids and antibiotics can also cause severe anxiety in many people. I had one dose of Steroid as a premed for my chemo and I was like a wild crazy woman. My whole body was shaking and I could not even hold a spoon - my hubby had to try to feed me. I think I am still picking up cheerios from that episode.
You may want to post in the anxiety forum as the members there will have great ideas for you.
I will keep you in my prayers,
