I am wondering which one has the potential to work better for my severe treatment resistant major depressive disorder. I'm also in a hurry to do one or the other, does anyone have any thoughts or experiences with this?

I have insurance but my psychiatrist said he could get them to approve spravato, but it will probably take some doing. I know I'm going to have to take out a loan for either treatment, so what's my best bet? If I can't get one or the other soon, I feel like I am going to have to check myself into a mental hospital.

Any thoughts, suggestions, or experiences would be SO appreciated. Thanks guys.
