Lemme tell you a story..

I had a sister with freudrix attacksia (highly misspelled there lol tbh), it's a muscular distrafy that gives the inflicted 20 years to live upon diagonosis. I watched her slowly get worse. First her legs went, then she developed swallowing problems, then ashma, then she couldn't even feed herself. This disease begins at the feet and destroys your nerve muscles slowly climbing its way towards the brain.

She always knew what was going on, what was wrong with her, and that she was going to die. She once tried to kill herself, once tried to run away, she had major mood swings. She wasn't a nuisance, she was my sister and I loved her, she was my mom's daughter and mom loved her. When she passed away, my mom went crazy (literally), and several people cried over losing her.

My point here is, though it may be tough at times, those around you know it's something you can't really control. They still care for you and about you (even when it doesn't seem that way at times), never lose sight of that. They'll be there for you when you need them, and though you may feel like you're a burden to them, they wouldn't stick around if they didn't care.
