Experiencing sinus pain/he aches, neck pain, vision issues, extreme sleepiness. Right side eye pain and ear pain. Ear feels full or stuffy. Ideas?

Possibly migraine. you are having a migraine issue. The ear pain may be from teeth clenching or grinding partly related to your anxiety or less likely an inner ear infection. You need to talk to your doctor and get examined. Glaucoma should be ruled out as the cause for the eye pain- get the eye pressure checked since it may lead to permanent loss in vision if left untreated. Good luck.
