Hi Mike, I ended up in a psych ward after an epic bender of booze and ADHD medication. I actually enjoyed myself during my stay. besides the terrible food and boredom, I was comforted that I have no serious mental illness and that substance abuse was the issue. I deal with depression and anxiety sometimes but it's manageable with therapy and meds. The booze is the main culprit of my issues.
If you are afraid you have health problems, where better to be than a safe place with doctors, right? give the hospital a chance to help you. I think they will find that you are not as ill-health as you think you are. take the help, you can sober up in the hospital as you're there and come out back on track.
