Separation Anxiety! Any suggestions on how to overcome/cope with it?

Lately I've been feeling really sick. Since my husband has started a new job my anxiety has been sky high. It affects my daily life. I cant eat, i barely sleep & I'm always nauseous. My stomach is always in knot. To the point of vomiting but i cant. After he leaves for work i have to take Tylenol with sleep aids just to get some rest while he is away. I think I'm going through separation anxiety again but this time its far more worse then when we separated for 3 months after we lost our first baby! I have anxiety pills that my doctor prescribed when i went through separation anxiety before. They really don't help much. Any suggestions on how to overcome his? I'm almost in tears everyday because i don't know what it is!
