I quit medications for years looking for other options to treat depressive episodes, BP 2, and PTSD diagnoses.
I found help with DBT, mindfulness and meditation as mentioned above, and the other skills they teach, which I continue to use to this day. I also use acupressure and acupuncture. I still use herbs as well to treat other things including the anxiety and the nightmares, such as gaba, in particular now has been a lifesaver.
I have, however, gone back on medication, but do not need as much as before, very small dosages in fact, and feel more balanced combining all of the above.
I hope you find what works best for you. It can be a matter of trial and error, but the right thing(s) are out there it is just a matter of patience, staying in tune with your mind and body, and knowing you will find it.
