Breasts look like that after the kind of surgery you had, exactly as you described. I attended to my mother-in-law after her surgery because of cancer. Hers got horribly infected. I'm thankful you have a drain so it can actually drain.
What can you do today, just for you? Jumping in puddles is probably not a good idea, but maybe a bit of Rum Cake to go with that Coke?? Hugs, LG. You are worth fighting for.
