Crude I didn't see this until now. I'm assuming that the house is in your mom's name. What are here thoughts on it? If you leave then she is forced to either sell it or find a renter, what a hassle in my opinion. I know it would be hard at first to stay but with a little bit of paint, rearranging, new bed, you'd be surprised at how fast the new memories would replace the old ones. Having no house payment would be a blessing with the way the economy is today.
I had a house and moved to an apartment when I got divorced. Totally regretted it. Taking my pups out all the time wears on me, especially when it's piss pouring rain and snowing or I don't feel well. I'd give anything to have my house back. I was forced to sell though because he'd let it go into foreclosure, turns out he used the money to pay off his truck (at least that's what I suspect). I also hated having to get rid of most my stuff because you can't squeeze a 1500 sq ft split level into a 1000 sq ft 2 bedroom apartment.
I know the emotions you are going through, trust me. But my vote is that if at all possible stay in the house. I know you need to do what makes you most comfortable though. I'm sending you good vibes and well wishes.
Take care, ah just saw that you already talked to your mom. I'd come help you move hun if you were closer.
