Michaela,
We are right there with you. And 16 months later, I still have times where I want to scream, want to be done with this, want to get my independence back completely, want to be "normal". I know how overwhelming this feels.
I know it's been said already, but one day at a time is the only way. When you have a day, where you wonder if it's going to be all right, if you can continue living this way, if you can one day be independent again... allow yourself to feel that way. I've found trying to push through those times or trying to make myself feel guilty that other's have it worse, only makes me more upset and depressed.
You are allowed to feel this way. But know you aren't alone. And tomorrow may not seem as bleak as today.
Take moment to enjoy a small pleasure... a piece of chocolate, a quiet time to yourself, noticing a small act of kindness someone does for you, etc. Its the small things around you and small victories you have to cling to. If you try to look too big picture, it can be too much. But the small things start to add up over time. You will be okay
