I’m almost 15 years in psychology and esoteric.
Different modalities that deal with blocks are:
Gestalt, NLP, Symbolic Modelling, Psychodrama, Systemic Constellations, PEAT and etc. etc. etc.
They are numerous, really. What I found is that combo of subs and working with somebody thru therapy brings best results.
You can try Breathing techniques, like Holotropic, Rebithing, Vivation (just google it). Most of them are easily done solo.
Btw, somebody mentioned Quantum Light Breath here, its active breathing meditation that removes blocks massively.
After 1-2 sessions of solo breathing I was able to manifest girl EXACTLY as I wanted.
Good luck
