anne i'm so sorry for what youre going through. i've been going through the same thing for weeks. this is whats worked for me. i sit on the edge of my bed or the edge of a chair and hold a pillow very tight and keep my eyes open and remind myself of who i am and where i am and that he is not there. i have olfactory hallucinations and sometimes i go crazy cleaning and that doesnt help. someone here told me about grounding techniques and they do work you just have to give it a chance. i am here if you need me.
wish i could take your pain away. hang in there.
