I’ve dealt with depression thoughout my treatment and it was worst earlier in my treatment and improved as I progressed/healed. All I can say is to hope that it improves and I would try out the supplements able mentioned. There’s another supplement you can take thats a homeopathic remedy that I know about that can aid with die off if you want me to share it…juniper berry extract would be the non-homeopathic version of this supplement.
I would also like to press that you should try out the black walnut extract; it works very well for me and I did experience a weird first few days of parasites die-off myself. It didn’t last that long for me, but the die-off did occur.
I wish you luck with your woes and hope you can find success with your treatment.
