During one of the imperial attacks on a stormcloak fort, I accidentally picked up a new horse. This caused Shadowmere to disappear (he had wandered off during the fighting) and I've been unable to find him. I've checked both sanctuaries, no luck there, and I've killed the new horse and waited a while. No shadowmere.
I've lost Shadowmere – where can I find her?
I've found this answer, but the difference is that I'm not sure where I got the new horse. I can't use commands since I'm on xbox.
Any tips, or will I have to say goodbye to my favorite destruction trainee?

There is a good chance that she is dead. Return to the position from where you fast traveled and you will probably find her corpse. Kill all the enemies in the region and wait 10 days, then she should appear when you fast travel again since companions are reset after 10 days if they die. If she doesn't appear, check the small lake in front of the falkreath sanctuary.
If not, try buying another horse and kill it. Shadowmere should become your default horse then and might "respawn" when you fast travel.
