Beginning again and again and again

If you could see where I'm starting from. One tiny room with all of my belongings. I'm on the third floor of my step father's home. I keep the door closed, trying to keep out the stench of cigarette smoke. I have an air purifier going, and I spritz the room with perfume a couple of times per day.
There's no bed, so for now I'm on the floor. It's actually not too bad. As long as I am able to catch a large chunk of uninterrupted sleep, I have no problem with sleeping on the floor.
My next challege will be paying my car insurance, parking ticket and meds. Giving up is not an option.
