I had the same problem I suggest, if you have one, reverting back to an earlier save before you installed your mods and try again once you gain your trainer companion one mod at at time. I made my game unplayable by installing too many mods at once and after hours of uninstall and reinstall of mods ended up completely reinstall Skyrim an installing mods after the character creation. Also just a tip, get BOSS to reorder your mods and always read and follow the mods install instructions and compatibility issues. Hope this helps
