If you have a brain disorder, do you still have hope for a better life?

I've realized that I have a serious problem with executive functions, which I believe are caused by a neurodegenerative disorder, I tried to focus on my studies but I was getting tired so fast and I couldn't keep my attention on the subjects. I don't have any motivation to do anything, I also felt extremely lonely and didn't have any friends, I don't know why but it feels like I'm living in some kind of dream, and I don't know what causes it.<br><br>I have no hope for a better life and I am depressed all the time, I don't know what to do.<br><br>&#x200B;<br><br>I don't know what I should do to make my life better.
