You have come to the right place to talk about what is happening to you. You will hear from several others who can relate to what you are going through. I have recently been hospitalized for anxiety so I know how you feel.
You are right to take some time off work to let the medication work. I am sorry your husband isn't understanding. My husband "tries" but he has never suffered from depression, anxiety or panic and just can't seem to put his mind around what is happening to me. Your husband is probably scared and needs some time to take it all in. The more he knows about your disorder, the more understanding he may be. But first, you have to get your panic under control. I hope your medication begins to work soon.
