Hang in there, Teresa.
I felt every second of every day on chemo was hell on earth, and from two weeks in I constantly threatened to quit treatment, so I can absolutely relate to what you're going through.
I can't say anything to make you feel physically better, but these are the things I used to help me get through it:
-I constantly reminded myself that I was taking this poison to increase my chances of being there for my daughter.
-I tried to remind myself that it would all be a memory at some point, that the suffering would not last forever.
-I bought a puppy both for company, distraction and to force myself to leave the house every day for a walk.
-I exercised every time I felt physically able.
-Any time I was able to eat, I binged on anything I was craving / anything I could stomach.
-I tried to focus on the beautiful, simple things in the world to distract myself.
-I rewatched countless old favourite movies and tv shows.
-I started collecting things, and spent hours online hunting for silly bargains.
-I attended Cognitive Behavioural Therapy to have someone neutral to spill my mind to, and to help give me the psychological tools to keep battling.
-I told myself if I completed treatment to the best of my ability and it still came back to kill me, at least I'd know I did literally everything I could to beat that monster.
Do not feel weak or defeated for taking a break, but please do follow your heart's intuition and make yourself continue with as much treatment as you possibly can. This will all be a memory soon, and you will be so proud of yourself for persevering through a torment most people cannot imagine - by the way, you already should be proud of yourself!
