My ENT suggested tonsillectomy/septoplasty together and removing Uvula. Will I have a hard time breathing? I get Claustrophobic

I'm 32 and have severe sleep apnea and constantly get tonsillitis. ENT wants to do tonsillectomy and septoplasty together along with removing the uvula. Just very nervous that I will have a panic attack if I can't breathe. I know the throat pain will be bad but more worried about breathing issues and feeling trapped. Any suggestions or should I be taking any anxiety medications? Can I breath through my nose since it's only tubbing? Thanks!
