Boston Terrier Separation Anxiety?

I have adorable 14 weeks old pup. He is deaf... There are few issues; he tends to eat his own feces/vomits when we are working day time. I took him out for a walk and went bathroom (make sure he poops) before I leave so he wouldn't eat his own feces during day time. I left lot of toys or treat in knok or ball where it will keep him busy for hours. It doesn't help. He would throw up his food, feces, and his own vomits. He would eat it again and throw up again. I could see all the spots/stain on the floor. When I come home, he was so nervous but excited to see me... he got scared when he throw up... will shake his head frequent and rubs his head on the floor/blanket. He would throw up few times when I first arrived; then he would stop afterward. When he is with me; he is total fine and he wouldn't eat his own fececs or vomit.
Also, I suspect that he may have separation anixety... he would follow me to everywhere, even only few inch away... He whines when I am in shower; he would want to jump in shower with me. Sometimes, when he is sleeping on my lap while Im watching tv, he would wake up starled, all of sudden, look around, or bark... then he realize I am still here and nothing is around He would go back to sleep. I love him so much but I felt helpless... I want him to feel comfortable and be okay when we are gone day time. He is so good with people, dogs, and listen to us.
