I Am really sorry to hear about this. I am by no means a doctor, or an expert, but seeing as how you are in the USA,  you may want to try ayahuasca. Just banisteriopsis caapi tea. ~50-100g taken once a week or so and see if this helps. You can add chaliponga leaves to the brew (DMT containing leaf) to potentiate the ayahuascas effects.

This is a semi legal option (iboga definitely is not, and also the internet iboga trade is contributing to Gabons rainforest destruction from what I have heard) and is also not as physically dangerous as iboga is, as ibogaine has been shown to cause rhythm fluctuations in one of the heart beats. Always good to get a heart panel and ekg before using iboga just to make sure you are good to go.

I can't say for sure whether or not these two things will help you, but I would say they are worthy of experimentation.  I hope you can find some relief and healing. Welcome to the DMT-Nexus! Keep us updated with your progress, please!
