Will I be able to get an appointment, or will I be locked away?

I'm sorry you have been feeling worse. It sounds like your depression is escalating. Now is the time to call and tell them you are not feeling safe and you feel like you are going to hurt yourself. Hopefully this will get some immediate response. They may be able to have you come in for an evaluation or they may advise you to go to the ER and see the Psychiatrist on call. Even if you need to go into the hospital, it's a good place to be when your are feeling so bad. You will be safe from yourself there. They will stabilize you on medication and help you make plans for treatment after your discharge. Please feel free to let us know how you are doing. Best Wishes to you.
