I know lots of people have posted things similar to this, but none of them are answering my question. So I got Shadowmere from Astrid a while back, and I recently got Frost as well, I also had a Riften horse since I can get those for free. My Riften horse died from falling from a great height, and my Frost died from fending off bandits, since I'd been missing Shadowmere for a while I decided to check and see if he was back at the Black Pool, but he was nowhere to be found. The last place I saw him was at Riften Stables but he's not there either, so that's basically it. Shadowmere can't die and when he does he just respawns, so I'm not sure where he could be. (I play on the Xbox 360 by the way.)

Well, I don't feel safe in my own room at night, but I feel that if I leave the room that i'll be even more vulnerable, and that If I go to sleep at night, that i'll wake up to see someone dangerous staring back at me. I'm not sure what's going on, and just want to know what's wrong. It's even affecting my eating habits, I almost never eat, and when I do I have to force myself to eat, and after i've eaten a little I start to feel as if i'm going to throw up. Like today, I was only able to eat one slice of pizza and that was all I could eat before feeling queasy. I really just don't know what's wrong with me, and i'd like a little help.
