The facility I went to here in Oregon was brand new, a very nice place, with a gathering room with fireplace and big TV. It only handled 20 people, with a women's wing and a men's wing. Thou shalt not enter the opposite sex wing! So, it wasn't in itself a hospital, but across the campus from the mother medical center.
I just got a pistol for my daughter to use - she's not old enough to buy one. She needed it for personal safety because we live out in the country. She was raped and sexually assaulted a month ago, hence the need for more security. I remember a question at the store about mental health, but I don't remember the wording. I didn't mention my stay at the facility two years ago, or that I see a psychotherapist weekly for suicidal ideation.
If you're on your parents' insurance policy, they, of course, will see it in their statements. Do you know what the coverage is for inpatient? I paid 30%, but I had a second stay not long after the first, and was treated very poorly, given no meds which put me in serious withdrawal, so I wrote a letter of complaint, and my first stay cost was greatly reduced and the second stay was at no cost to me. It pays to write a good letter of complaint and send it to as many upper level staff as you can.
One other thing is that you may already have a strike because you took Lexapro, sending the insurance company a red flag for depression. That really messes things up if you try to change plans or companies because they'll see you as a high risk.
If Lexapro didn't work (assuming you took it for at least six weeks), you should try another antidepressant. There are lots of them out there, and you may have to try a dozen before you find the right one. For most of them, you can't know that it will work or not for you until you take them for six weeks. A real bummer because you're getting more and more depressed while you search for the right one.
I had to take a real attitude check when I became deeply depressed. My wife and doctors kept pointing out to me that if I had broken my leg and had to be hospitalized, there would be no stigma attached. Mental illness is no different from illnesses from the neck on down. I told my immediate superiors, and then down the road after I came home from the hospital I went public with it, and suffered a lot of negativity from people. So, you have to weigh the benefits against the difficulties.
May God give you strength and wisdom as you take this journey. You need all the help available.
