Angel, oh how I understand your pain.
My father had bladder cancer, and had to go in for surgery. They said he would be in and out in a week, but things got complicated, and he ended up in the hospital for three months. Each and every day my mother and I would drive to work together, then stop by the hospital on the way home, get home at some ungodly hour, eat, and go to bed - and then repeat it all the next day. For three months.
On top of that, my mother would be fine while we were in the hospital with my father, but then when we got home, she’d let it all out - so, in effect, I was taking care of two ailing parents. It was a nightmare, and thank God I was dating Dr. Boyfriend at the time who not only helped me understand the medical stuff, but was extremely understanding the two times I myself snapped from the pressure.
Now I have two older sisters, the oldest (known as the good sister) and the middle (known as the evil sister). The good sister would make it down probably once or twice a week, but she has four kids and she’s an hour away, so no easy feat. The evil sister I think made it out to see him three times the entire time he was hospitalized, and she only has two kids (but she’s a bitch, which is another Pit rant entirely). Ergo, everything was basically left to me.
So Dad gets out of the hospital, all is well, and so forth. Fast forward about two years - I’ve moved to California, and one reason is all this that happened (and not wanting to go through it again should, God forbid, the worst happen). Dad goes to the hospital for a checkup, and lo and behold, the cancer’s back - six weeks of chemo and radiation are prescribed (not nearly as radical as surgery, but scary nonetheless). The good sister decides to pick up the ball and go to some of their appointments with them to make sure she understands everything and everything is alright.
After three appointments she calls me and says, “I’m exhausted - how did you do it for three months?!?!”
Aaaaaaaaaaaaaaaaah, the sweet feeling of validation. 
And someday, lass, it will come to you as well.
(So far Dad’s fine, although on the heels of this they found out the house is falling apart from termites and Mom got diagnosed with diabetes, but so far so good… I hope! 
)
