can\'t sleep again

It is 2:10 in the morning, and I can't sleep again. I brought my computer out into the living room so that I wouldn't keep the girl awake, and I sit here completly awake. I took another anti-anxiety pill, becuse I'm not up to maximum dosage for the day  I usually don't take the max because it knocks me out and I don't like that, but by golly, I need sleep.  I worked hard today, trying to set up the room so that my brother's stuff can get out of the loft and we can shut down the heater up there. The extra heat is driving me bankrupt.  I'm feeling desperate. When I moved up here it was more to get away from the life I was living in RI than going to something. Well, my prioities changed when my daughter asked me to adopt her daughter to save her from foster care.  Now I'm here, and so is she, and neither one of us is happy here. Once again I feel like leaving, but am I once again getting away from something rather than going towards something? Is that wrong? I've been unhappy most of my adult life, and no matter where I go I bring that with me. And I've been doing this alone. Even when I was married, for 16 years, I was going through it alone. I think that is why I brought my brother up here with me when I came, because I didn't want to do it alone, but just like all the other people I've ever shared my life with, he is a drain.  I'm so desperately alone.
