Not Sure What To Call This...

There are some days I just don't know what to name my post. This is one of them.
Our family had another bombshell dropped on us last night. It started when I was getting ready to pick up my friend for some yoga when I got a text from my brother saying I needed to run up to my dads cause something was wrong. He wasn't sure what was wrong other than my step-mom was really worried about my dad. Brandon was on his way home so I called him and had him go straight to my dad's instead of coming home. When I got there, my sister, sister-in-law, step-sister, and Brandon were there getting my dad ready to go to the ER. I asked what was going on and they said that he has been acting really 'funny' the past week or so. He hadn't been talking really at all. If anyone knows my dad you know that is VERY strange that he wasn't talking especially for a week. Also, he would take a very long time to answer when you asked him a question. It was almost like he was 'slow' even though normally he is quick as a whip. I had Brandon take Sawyer home while I went to the emergency room with them. When we got there they asked him questions and again he wouldn't respond for a long time, he didn't know what the date was, and he almost seemed kinda vacant at times. They drew his blood and took a urine sample to check for any kind of abnormalities or infections. Those came back clean. They took him for an MRI and once those results came back we were all quite shocked to hear what they showed. They found lesions in his cerebellum. The cerebellum controls your balance/stability and is the center for your respiratory. Not a good place to have cancerous lesions.
After they told us this disturbing news, they released my dad and let him go home. While I drove home I started thinking about what this all meant. He's had cancer for almost 2 years now and has been doing chemo for a while also. He's slowly declined in health and has changed in so many ways I almost don't recognize him. He was always so strong. For example, he would always show off by tearing a large very thick phone book in half! I was always so proud to show off that trick to my friends! He is a very tall man and was always very muscular but now he is so thin and feeble it blows me away when I see him. He always looked very young for his age but now he seems to have aged 20 years. As I mentioned before, his mind was always quick as a whip but now he is forgetting things constantly, doesn't seem to follow a conversation like he once did, and seems vacant. When he looked at me in the ER, he reminded me of a child looking back at me. Its just so strange to see my father so helpless. Its kind of shaking my world around. The Dr in the ER told him what they found in the MRI then said for more information about the lesions he'd have to see his regular oncologist. I went and saw him today and he wasn't able to get into his oncologist which really bugs me. While I was at my dad's he didn't really say much at all the whole time. He'd also fell earlier that morning while he was in the shower and bruised his arm pretty bad. We decided it was no longer a good idea for him to be walking alone or standing while showering. With the lesions in is cerebellum, they are definitely throwing off his balance. If he were to fall and break lets say a hip.... I don't think he'd last. And frankly, I'm too young to lose a parent. So for now we just have to wait until he can get into see his oncologist. Cancer.... such an ugly thing.
I told my mom she was not allowed to get any kind of cancer. That goes for all my parents, siblings, aunts, uncles, cousins, friends, children, and acquaintances! Lets hope they all listen...
