Well first of all- hang in there! Things always look bleak when we're inside them. But.. I've found thing often ease up a bit.

'Let'? Mental illness or not, you're a grown woman. Unless he's got you under lock and key I don't know about this 'let' business. Don't let him discourage you.
You write about how I feel when I'm really short on rest, and really anxious. Please try and rest- try and go to bed at a decent time and put the devices down- or if, like me, sometimes your mind gets racing, think about putting on something you've watched a thousand times but aren't so emotionally invested in you have to watch it- just listen to the audio to keep your thoughts from getting away from you. That helps me sleep when I'm in a really bad headspace.
I know it can be scary being on your own. I'm partnered for nearly a couple decades, now, and I notice I am much more anxious when out alone, than I used to be. But I make myself do things, anyway. It's absurd I should be anxious over being out by myself when 20 years ago I thought much less of it. And in a time I didn't have a cell phone, too.
But baby steps. Try getting out close to the house a short while. Try.. seeing that brother near you, if you can. You have to start somewhere. I'm OCD, and with OCD I get in these mental repetitive circles and I have to break the loop by doing something out of my comfort zone. Once I manage to do that, then things get easier to deal with. I feel as if that's what you have to do, here. Try and get outside a little.
