Hi, I have lung cancer and currently having radiation therapy..I use self hypnosis/yogic breathing to get me through my treatments and when I’m overwhelmed or overthinking everything… there are lots of short 5-10 min videos both hypnosis & worry, stress and pain on you tube to help you get started, explore if this is for you ..start with just short times and guided meditations they are easier, then you can expand the time as you want to… I have also had autoimmune problems (where my immune systems attack me) fibromyalgia you will probably have heard of and have had to come off all my treatents that control that so I’m feeling like the tin man left out in the rain lol, all stiff & swollen joints, so I’m using meditation to help with that as well.. also at my cancer unit there is alway MacMillan staff around & a holistic team who can offer things like aromatherapy, reiki etc so that might be worth looking into …Best of luck at this difficult time, I do hope you find something that helps
