I have not yet attempted any Therapy. But as places are SOOO rare, and real deep psychological therapy takes often over 2 years, I dont believe this can work.
I had extremely intense, deep and healing experiences on Cannabis and LSD though. Cannabis was really bringing me to my feelings, subconsciousness, addictions, stress. LSD made me understand how my brain works a bit better.
Especially psychedelics are said to increade neuroplasticity, and they cause "crazy neuron firing", to regions they normally dont do. This was extensively used in psychotherapeutic studies and also applocation, but then some stupid people where scared of it and banned it along with some other racistically motivated bans.
I firmly believe that psychedelic therapy, together with a retreat, nature, dancing, and so on, is the only real way one can heal.
