Post treatment anxiety

Hi everyone! I completed my treatment wuth success for my NLPHL about 3 weeks ago.

I really want to enjoy the time I have no matter what happens. Ive come to a rational understanding I have no control over it, but I can Control my everyday and live with enjoyment.

Thing is im still in a state of hyper alerteness, not necessarily about the lymphoma, but about everything… Any mild pain or discomfort I immediately worry, as well as having some residual anxiety feelings. Im doing therapy but the issue is more how do I get out of this every day loop that tales a fair chunk of my mental energy. The moment I have any minor issue or pain I treat it almost like a medical emergency and catastrophize.

Just looking for advice generally if there was anything that helped your mind transition into feeling more safe and normal. Anything that helped ease the anxiety.
