I am sorry lucy about treatment. I just went through the same thing and it sent me into a deep dark hole of depression for a couple weeks. But my friends here and my gram helped me through it.
HAve you considered IOP (Outpatient) . That seems to be easier to get into with any insurance. Alot of insurance companies dont want to pay residential. But will do outpatient.
I hope you feel better soon and find some help.
