I went through a breakup like situation with an ex a few years ago and developed anxiety almost immediately, accompanied with auditory hallucinations. After a few days of it my friend suggested I drink. I do not know if I'll still have the anxiety when I'm sober but I feel a racing heart currently. I'm fearing having insomnia tonight but hoping the Benadryl works. I think the fear of people knowing my habits is bringing on the racing heart. I will consider seeing a doctor if the withdrawal gets out of hand tomorrow. Is that something I can go to the ER for?
