Exhausted, frustrated and Concerned

My morning began between 5 and 5:30 when I got up to take Toby out, do my mom's readings and give her her morning medicine and juice. I knew there was a problem as soon as I was in the hall. Something stank. Badly. Entering my mom's room I saw what looked like a crime scene, but in shit instead of blood. Toby had had BAD diarrhea on her bed and he and my mom were sleeping obliviously in the middle of it. I took her readings first, then took Toby out and then to the groomery to bathe him. The excrement was so dried on it took 4 shampoo-ings to get it all off. I am sure he felt better after the bath. Then I stripped the bed down to the fitted sheet (which I thought was clean) and started trying to get the bedding clean. Lots and lots and lots of laundry. I had planned to do my bedding and other laundry today, but so far the machine is commandeered. My mom wanted hotcakes for breakfast and so I made some. I can't remember ever making worse tasting hotcakes and I can't think what went wrong, I mean, it's not rocket science! My mom has a Dr's appointment and labs today and even though I try to take how slow she is under consideration we didn't get there till 1 (they wanted us there at 12:45) She won't let me use the wheelchair I got for her and she did indeed fall in the dr's office. She gained about 25 pounds which is incredible to me because she eats so very very little. The first reading of her blood oxygen at the Dr's, which was taken right after she was back in a chair after the fall was 79. Not good! They later took it again and it was 90 which is better but still not terrific. I had the Dr look at her feet because I am noticing edema and her toes are purplish. She was mad at me for that and madder at Bruce because she thought it was at his instigation even though I told her I have been concerned and rightfully so because with diabetes, paying attention to one's feet is critical. She gave 5 tubes of blood for labwork. I discusses diarrhea with her Dr who advised me to bring it up with the nephrologist next Thursday. We're reducing her Lantus from 10 to 8 at night because her morning readings are so low. I told her Dr I am not giving her Lantus if her blood sugar is 200 or lower. Thankfully he agreed with that strategy. I took home a hat and a sample cup to do the urine sample at home. I'll take it back later. She can never manage to pee in a Dr's office even if she drinks water which she did. After the appointment she just wanted to come home. she was worried about Toby (and indeed he has crapped all over the floor of her room and smeared it everywhere- another bleach job for me today) Bruce changed her sheets all the way while we were gone and I am doing even more laundry. Getting her in the front door, my heart was in my throat and even though both Bruce and I were spotting her she went down AGAIN in the cement and bumped the back of her head. The lady across the street came running over with a blanket to help. My mom needs to lay there awhile before she wants us to try to help her up. I hope the lady doesn't think I was rude to send her away, but it's not a quick fix. Nothing with my mom is quick anymore. Things work better if we go at her very slow pace. I'll get a thank you card for the lady and try to explain. Once she was in the house my mom just wanted to lay down, so she didI added a pressure releasing pad under her. Bruce went to check on her a few minutes ago and she is asleep. I'm going to need to wake her up to get the urine sample. That makes me feel bad, but they close ar 5. I told Bruce I am considering getting my mom a helmet. He suggested kneepads too. I'm grateful for him. He really cares about my mom and checks on her many times a day.
