The state you are in an ordinary outpatient doc can do nothing. You need to go inpatient and do it now. You need someone to help you with hygiene, proper eating and exercise. You need someone to really have you on the right meds. It's a big step but it's what you need to do. Your old doc has no idea what has kept you away, they probably thought you did fairly OK not staying in touch. So realizing it was an emergency, calling an ambulance was proper advice.

You cannot just live in an online world and let everything else deteriorate. Get some help, please.
