Livid and dizzy

Made it 5yrs out from Stage 2 triple positive BC, in January ‘25 got moved to yearly checks. Just had clear mammograms in April ‘25 and 2 months later, I get rocked with a brain lesion. I have done 3 radiation sessions, wrapping up the last two in July, but the swelling and steroids are not cool. Even going on a car ride can be too much activity for me. I’m so angry. I worked out, ate well, went to my checkups and I’m back in unknown territory. Will I get my life back? I need a freakin vacation. This sucks.
